　無線受信駆動装置をおもちゃ乗り物の電池ボックスに装着した状態で、無線受信駆動装置に対して、おもちゃ乗り物のモータ及び外部スイッチが直列に接続される。モータ等の誘導性負荷のオン／オフに伴って、モータには逆起電力による高いサージ電圧が発生する。モータでのサージ電圧の発生は、モータに接続されている無線受信駆動装置の基板の破損につながる。また、無線受信駆動装置に対して直列に外部電池が接続される場合がある。このように無線受信駆動装置が使用された場合、電動式おもちゃ乗り物のスイッチがオン状態であれば、おもちゃ乗り物が動いていない状態であっても、無線受信駆動装置の基板に外部電池のリーク電流が流れ込み、それにより外部電池が消耗してしまう可能性がある。 In the state where the wireless reception drive device is mounted on the battery box of the toy vehicle, the toy vehicle motor and the external switch are connected in series to the wireless reception drive device. As an inductive load such as a motor is turned on / off, a high surge voltage due to counter electromotive force is generated in the motor. Generation of a surge voltage in the motor leads to breakage of the substrate of the wireless reception driving device connected to the motor. In some cases, an external battery is connected in series to the wireless reception driving device. When the wireless reception driving device is used in this way, if the electric toy vehicle is switched on, the leakage current of the external battery on the substrate of the wireless reception driving device even if the toy vehicle is not moving May flow, and the external battery may be consumed.

Specifically, the wireless communication function of the battery-type power supply device 100 is turned on / off in conjunction with the power switch 114 being turned on / off. FIG. 4 is an equivalent circuit diagram illustrating an example of the battery-type power supply device 100 according to the first embodiment. Here, the battery-type power supply device 100 is attached to the battery box 112 so as to be connected in series to an external battery. A built-in battery is mounted in the battery housing portion 102 of the battery-type power supply device 100.
　（回路構成）　
　第１実施形態に係る電池形電源装置１００は、出力トランジスタ１２０、ＤＣＤＣコンバータ（内部電源回路）１２１、ＲＦＩＣ（制御回路）１２２、インバータ１２３、プルアップ抵抗（検出抵抗）１２４、プルアップ抵抗１２５及びリーク電流防止部１７０を有する。これら電子部品は基板１０７に実装される。 (Circuit configuration)
The battery-type power supply device 100 according to the first embodiment includes an output transistor 120, a DCDC converter (internal power supply circuit) 121, an RFIC (control circuit) 122, an inverter 123, a pull-up resistor (detection resistor) 124, a pull-up resistor 125, A leakage current prevention unit 170 is included. These electronic components are mounted on the substrate 107.
　出力トランジスタ１２０は、典型的にはＰチャンネルＭＯＳＦＥＴであり、内側正極端子１０５と外側正極端子１０３との間に介在される。出力トランジスタ１２０のソース端子は、配線ケーブル１０９を介して内側正極端子１０５に接続される。出力トランジスタ１２０のドレイン端子は、配線ケーブル１１０を介して外側正極端子１０３に接続される。 The output transistor 120 is typically a P-channel MOSFET, and is interposed between the inner positive terminal 105 and the outer positive terminal 103. The source terminal of the output transistor 120 is connected to the inner positive terminal 105 via the wiring cable 109. The drain terminal of the output transistor 120 is connected to the outer positive terminal 103 via the wiring cable 110.
　プルアップ抵抗（検出抵抗）１２４は、内側正極端子１０５と外側正極端子１０３との間に、出力トランジスタ１２０と並列に配置される。プルアップ抵抗１２５は、出力トランジスタ１２０のゲート端子と内側正極端子１０５との間に介在される。 The pull-up resistor (detection resistor) 124 is disposed in parallel with the output transistor 120 between the inner positive terminal 105 and the outer positive terminal 103. The pull-up resistor 125 is interposed between the gate terminal of the output transistor 120 and the inner positive terminal 105.
　ＤＣＤＣコンバータ１２１のＶｃｃ端子は内側正極端子１０５に接続され、ＥＮ端子は外側正極端子１０３に接続され、ＯＵＴＰＵＴ端子はＲＦＩＣ１２２のＶｄｄ端子に接続される。ＤＣＤＣコンバータ１２１は、内部電源回路であり、電池収納部１０２に装着された単４乾電池の電池電圧Ｖccを内部回路動作用の例えば３．０Ｖの電源電圧Ｖｄｄに昇圧する。ＤＣＤＣコンバータ１２１は、そのＥＮ端子がハイレベルのとき電源電圧ＶｄｄをＲＦＩＣ１２２に給電し、そのＥＮ端子がローレベルのとき電源電圧ＶｄｄをＲＦＩＣ１２２に給電しないように構成されている。ここでは、ＤＣＤＣコンバータ１２１がＲＦＩＣ１２２の駆動電圧を給電する内部電源回路として機能するが、ＲＦＩＣ１２２に駆動電圧を給電する内部電源回路はＤＣＤＣコンバータ１２１以外の他の電子部品等であってもよい。 The Vcc terminal of the DCDC converter 121 is connected to the inner positive terminal 105, the EN terminal is connected to the outer positive terminal 103, and the OUTPUT terminal is connected to the Vdd terminal of the RFIC 122. The DCDC converter 121 is an internal power supply circuit, and boosts the battery voltage Vcc of the AAA dry battery mounted in the battery storage unit 102 to a power supply voltage Vdd of, for example, 3.0 V for internal circuit operation. The DCDC converter 121 is configured to supply the power supply voltage Vdd to the RFIC 122 when the EN terminal is at a high level, and not to supply the power supply voltage Vdd to the RFIC 122 when the EN terminal is at a low level. Here, the DCDC converter 121 functions as an internal power supply circuit that supplies the driving voltage of the RFIC 122, but the internal power supply circuit that supplies the driving voltage to the RFIC 122 may be an electronic component other than the DCDC converter 121.
　出力トランジスタ１２０のドレイン端子とＤＣＤＣコンバータ１２１のＥＮ端子との間にはインバータ１２３が介在される。ＤＣＤＣコンバータ１２１の入力段にインバータ１２３を配置することで、モータ１１５に発生する逆起電圧によるＤＣＤＣコンバータの破壊等を回避することができる。インバータ１２３の入力端子は出力トランジスタ１２０のドレイン端子に接続され、出力端子はＤＣＤＣコンバータ１２１のＥＮ端子に接続される。インバータ１２３は、入力信号を反転して出力する。 An inverter 123 is interposed between the drain terminal of the output transistor 120 and the EN terminal of the DCDC converter 121. By disposing the inverter 123 at the input stage of the DCDC converter 121, it is possible to avoid destruction of the DCDC converter due to the counter electromotive voltage generated in the motor 115. The input terminal of the inverter 123 is connected to the drain terminal of the output transistor 120, and the output terminal is connected to the EN terminal of the DCDC converter 121. The inverter 123 inverts the input signal and outputs it.
　ＲＦＩＣ１２２は、電源電圧Ｖｄｄで駆動し、電池形電源装置１００を統括して制御する制御回路である。ＲＦＩＣ１２２のＡＮＴ端子には無線通信用のアンテナ１２７が接続される。ＲＦＩＣ１２２のＯＵＴＰＵＴ端子は出力トランジスタ１２０のゲート端子に接続される。ＲＦＩＣ１２２は、機能上、通信部、制御信号発生部、制御部等を備える。通信部は、制御部の制御に従って駆動され、アンテナ１２７を介して外部情報処理装置２００とBluetooth(登録商標)規格に準拠した無線通信を行う。なお、ＲＦＩＣ１２２は、他の無線通信規格、例えば無線ＬＡＮ規格に準拠した無線通信を行ってもよい。通信部は、アンテナ１２７を介して外部情報処理装置２００からモータ１１５のオン／オフを表すコード無線信号を受信する。モータ１１５のオンを表すコード無線信号を受信したとき、制御信号発生部は、制御部の制御に従って駆動され、ローレベルのゲート制御信号を発生する。モータ１１５のオフを表すコード無線信号を受信したとき、制御信号発生部は、制御部の制御に従って、ハイレベルのゲート制御信号を発生する。または、制御信号発生部は、制御部の制御に従ってオフされ、それによりＯＵＴＰＵＴ端子は開放される。制御信号発生部により発生されるゲート制御信号のハイレベルとは、出力トランジスタ１２０のしきい値電圧Ｖthよりも十分低い電圧値であり、ローレベルとは、出力トランジスタ１２０のしきい値電圧Ｖthよりも十分高い電圧値である。 The RFIC 122 is a control circuit that is driven by the power supply voltage Vdd and controls the battery-type power supply device 100 in an integrated manner. An antenna 127 for wireless communication is connected to the ANT terminal of the RFIC 122. The OUTPUT terminal of the RFIC 122 is connected to the gate terminal of the output transistor 120. The RFIC 122 functionally includes a communication unit, a control signal generation unit, a control unit, and the like. The communication unit is driven under the control of the control unit, and performs wireless communication with the external information processing apparatus 200 via the antenna 127 in conformity with the Bluetooth (registered trademark) standard. Note that the RFIC 122 may perform wireless communication complying with another wireless communication standard, for example, a wireless LAN standard. The communication unit receives a code wireless signal indicating on / off of the motor 115 from the external information processing apparatus 200 via the antenna 127. When the code wireless signal indicating ON of the motor 115 is received, the control signal generator is driven according to the control of the controller and generates a low level gate control signal. When the code wireless signal indicating that the motor 115 is turned off is received, the control signal generation unit generates a high-level gate control signal according to the control of the control unit. Alternatively, the control signal generator is turned off in accordance with the control of the controller, thereby opening the OUTPUT terminal. The high level of the gate control signal generated by the control signal generator is a voltage value sufficiently lower than the threshold voltage Vth of the output transistor 120, and the low level is higher than the threshold voltage Vth of the output transistor 120. Is a sufficiently high voltage value.
　出力トランジスタ１２０は、ゲートに入力されるゲート制御信号により印加される電圧（ゲート電圧）により、そのオン／オフが制御される。ゲート電圧がしきい値電圧Ｖthよりも十分低いローレベルであるとき、ソース・ドレイン間にチャネルが形成され、最大ドレイン電流が流れる。この状態は出力トランジスタ１２０がオン状態である。出力トランジスタ１２０がオンされると、電池形電源装置１００の外側正極端子１０３と外側負極端子１０４との間に内蔵電池を介して電流が流れる。外部負荷装置１１１の電源スイッチ１１４がオン状態であれば、電池形電源装置１００の外側正極端子１０３と外側負極端子１０４との間に電流が流れ、外部負荷装置１１１のモータ１１５が駆動する。一方、ゲート電圧がしきい値電圧Ｖthよりも十分高いハイレベルであるとき、ソース・ドレイン間にドレイン電流が流れない。この状態は出力トランジスタ１２０がオフ状態である。出力トランジスタ１２０がオフされると、電池形電源装置１００の外側正極端子１０３と外側負極端子１０４との間が遮断される。これにより、外部負荷装置１１１の電源スイッチ１１４がオン状態であっても、外部負荷装置１１１の回路は遮断され、モータ１１５は駆動しない。 The output transistor 120 is controlled to be turned on / off by a voltage (gate voltage) applied by a gate control signal input to the gate. When the gate voltage is at a low level sufficiently lower than the threshold voltage Vth, a channel is formed between the source and the drain, and the maximum drain current flows. In this state, the output transistor 120 is on. When the output transistor 120 is turned on, a current flows between the outer positive terminal 103 and the outer negative terminal 104 of the battery-type power supply device 100 via the built-in battery. If the power switch 114 of the external load device 111 is in the ON state, a current flows between the outer positive terminal 103 and the outer negative terminal 104 of the battery type power supply device 100, and the motor 115 of the external load device 111 is driven. On the other hand, when the gate voltage is at a high level sufficiently higher than the threshold voltage Vth, no drain current flows between the source and the drain. In this state, the output transistor 120 is off. When the output transistor 120 is turned off, the outer positive terminal 103 and the outer negative terminal 104 of the battery-type power supply device 100 are disconnected. Thereby, even if the power switch 114 of the external load device 111 is in the ON state, the circuit of the external load device 111 is cut off and the motor 115 is not driven.
　保護用ダイオード１７１は、モータ１１５に対して出力トランジスタ１２０と並列に、外側負極端子１０４から外側正極端子１０３に向かって順方向となるように配置される。ツェナーダイオード１７２は、保護用ダイオード１７１と逆向きに配置される。ここでは、保護用ダイオード１７１及びツェナーダイオード１７２は、外側正極端子１０３と外側負極端子１０４との間にモータ１１５に対して出力トランジスタ１２０及び内蔵電池に並列に接続される。保護用ダイオード１７１の入力端子は外側負極端子１０４に接続され、出力端子はツェナーダイオード１７２の出力端子に接続され、ツェナーダイオード１７２の入力端子は外側正極端子１０３に接続される。 The protective diode 171 is arranged in parallel with the output transistor 120 with respect to the motor 115 so as to be in the forward direction from the outer negative terminal 104 toward the outer positive terminal 103. The Zener diode 172 is disposed in the opposite direction to the protective diode 171. Here, the protective diode 171 and the Zener diode 172 are connected in parallel to the output transistor 120 and the built-in battery with respect to the motor 115 between the outer positive terminal 103 and the outer negative terminal 104. The input terminal of the protective diode 171 is connected to the outer negative terminal 104, the output terminal is connected to the output terminal of the Zener diode 172, and the input terminal of the Zener diode 172 is connected to the outer positive terminal 103.
　ツェナーダイオード１７２のツェナー電圧と保護用ダイオード１７１の順方向電圧との合計電圧は、出力トランジスタ１２０の逆降伏電圧の絶対値よりも小さい。それにより、出力トランジスタ１２０のオン／オフに伴って、モータ１１５で瞬間的にサージ電圧（逆起電圧）が発生しても、サージ電流が保護用ダイオード１７１とモータ１１５とを含む閉回路で消費される。それにより出力トランジスタ１２０のドレイン－ソース間に高電圧がかかることを回避することができ、出力トランジスタ１２０をモータ１１５で発生したサージ電圧から保護することができる。 The total voltage of the Zener voltage of the Zener diode 172 and the forward voltage of the protective diode 171 is smaller than the absolute value of the reverse breakdown voltage of the output transistor 120. Accordingly, even if a surge voltage (counterelectromotive voltage) is instantaneously generated in the motor 115 as the output transistor 120 is turned on / off, the surge current is consumed in a closed circuit including the protection diode 171 and the motor 115. Is done. Thereby, it can be avoided that a high voltage is applied between the drain and source of the output transistor 120, and the output transistor 120 can be protected from the surge voltage generated by the motor 115.
　また、ツェナーダイオード１７２のツェナー電圧と保護用ダイオード１７１の順方向電圧との合計電圧は、少なくとも外部電池３００の合計電圧よりも大きい。それにより、外部スイッチ１１４がオンされた状態で、出力トランジスタ１２０が定常状態であるとき、つまり、外部スイッチ１１４がオン状態でモータ１１５でサージ電圧が発生していないとき、ツェナーダイオード１７２にはツェナー電圧よりも低い逆方向電圧しかかからないため、ツェナーダイオード１７２はオフ状態である。保護用ダイオード１７１とモータ１１５とを含む閉回路はツェナーダイオード１７２により遮断され、それにより外部電池３００によるリーク電流の発生を防止又は低減することができる。なお、外部スイッチ１１４と出力トランジスタ１２０とが共にオン状態であるとき、保護用ダイオード１７１にはダイオードの逆降伏電圧よりも低い逆方向電圧しかかからないため、保護用ダイオードはオフ状態である。そのため出力トランジスタ１２０と内蔵電池と保護用ダイオード１７１とを含む閉回路は保護用ダイオード１７１により遮断され、それにより内蔵電池のショートを回避することができる。 Further, the total voltage of the Zener voltage of the Zener diode 172 and the forward voltage of the protection diode 171 is at least larger than the total voltage of the external battery 300. Thus, when the output transistor 120 is in a steady state with the external switch 114 turned on, that is, when the external switch 114 is on and no surge voltage is generated in the motor 115, the Zener diode 172 has a Zener diode 172. Since only a reverse voltage lower than the voltage is applied, the Zener diode 172 is in the OFF state. The closed circuit including the protective diode 171 and the motor 115 is interrupted by the Zener diode 172, thereby preventing or reducing the occurrence of leakage current by the external battery 300. When both the external switch 114 and the output transistor 120 are in the on state, the protective diode 171 is applied with a reverse voltage lower than the reverse breakdown voltage of the diode, and thus the protective diode is in the off state. Therefore, the closed circuit including the output transistor 120, the built-in battery, and the protective diode 171 is blocked by the protective diode 171, thereby avoiding a short circuit of the built-in battery.
　（動作説明）　
　以下、電源スイッチ１１４がオフされている状態を外部負荷装置１１のオフ状態、電源スイッチ１１４がオンされているがモータ１１５が動作していない状態を外部負荷装置１１１の待機状態、モータ１１５が動作している状態を外部負荷装置１１１の動作状態という。また、ＲＦＩＣ１２２の制御部が駆動していない状態を電池形電源装置１００のオフ状態、ＲＦＩＣ１２２の制御部は駆動しているが、無線通信部による送受信動作がオフされている状態を電池形電源装置１００の待機状態、無線通信部による送受信動作がオンされている状態を電池形電源装置１００の通信可能状態、ＲＦＩＣ１２２からゲート制御信号が出力されている状態を電池形電源装置１００の動作状態という。 (Description of operation)
Hereinafter, when the power switch 114 is off, the external load device 11 is off, when the power switch 114 is on but the motor 115 is not operating, the external load device 111 is on standby, and the motor 115 operates This state is referred to as an operating state of the external load device 111. Further, the state in which the control unit of the RFIC 122 is not driven is in the off state of the battery-type power supply device 100, and the state in which the control unit of the RFIC 122 is being driven but the transmission / reception operation by the wireless communication unit is off is the battery-type power supply device. The standby state of 100, the state in which the transmission / reception operation by the wireless communication unit is turned on is referred to as a communicable state of the battery-type power supply device 100, and the state in which the gate control signal is output from the RFIC 122 is referred to as the operation state of the battery-type power supply device 100.
　第１実施形態に係る電池形電源装置１００の一つの特徴は、電源スイッチ１１４のオン／オフに連動して、外側正極端子１０３の、基準電位に対する電圧レベルが変動するように、内側正極端子１０５と外側正極端子１０３との間に出力トランジスタ１２０と並列にプルアップ抵抗（検出抵抗）１２４を配置したことにある。ここでは、基準電位はＧＮＤ電位とする。電源スイッチ１１４がオフされているとき、外側正極端子１０３はプルアップ抵抗１２４を介して内側正極端子１０５に接続されるため、ハイレベルである。一方、電源スイッチ１１４がオフからオンに切り替わると、外側正極端子１０３は電源スイッチ１１４を経由してＧＮＤに接続されるため、ハイレベルからローレベルに切り替わる。このように、電源スイッチ１１４のオン／オフに連動して外側正極端子１０３の電圧レベルは変動する。電池形電源装置１００は、外側正極端子１０３の電圧レベルの変動を検出することで、電源スイッチ１１４のオン／オフを検出する。 One feature of the battery-type power supply device 100 according to the first embodiment is that the inner positive terminal 105 is configured so that the voltage level of the outer positive terminal 103 with respect to the reference potential varies in conjunction with the on / off of the power switch 114. In other words, a pull-up resistor (detection resistor) 124 is arranged in parallel with the output transistor 120 between the outer positive terminal 103 and the outer positive terminal 103. Here, the reference potential is set to the GND potential. When the power switch 114 is turned off, the outer positive terminal 103 is connected to the inner positive terminal 105 via the pull-up resistor 124 and is therefore at a high level. On the other hand, when the power switch 114 is switched from OFF to ON, the outer positive terminal 103 is connected to GND via the power switch 114, and thus switches from the high level to the low level. In this way, the voltage level of the outer positive terminal 103 varies in conjunction with the on / off of the power switch 114. The battery-type power supply device 100 detects ON / OFF of the power switch 114 by detecting a change in the voltage level of the outer positive terminal 103.
　外部負荷装置１１１が初期状態であるとき、インバータ１２３の入力端子はプルアップ抵抗１２４を介して内側正極端子１０５に接続されるためハイレベルであり、ＤＣＤＣコンバータ１２１のＥＮ端子（インバータ１２３の出力端子）はローレベルである。したがって、ＤＣＤＣコンバータ１２１により発生された電源電圧ＶｄｄがＲＦＩＣ１２２に給電されない。そのため、電池形電源装置１００はオフ状態である。 When the external load device 111 is in the initial state, the input terminal of the inverter 123 is connected to the inner positive terminal 105 through the pull-up resistor 124 and is therefore at a high level, and the EN terminal of the DCDC converter 121 (the output terminal of the inverter 123). ) Is low level. Therefore, the power supply voltage Vdd generated by the DCDC converter 121 is not supplied to the RFIC 122. Therefore, the battery-type power supply device 100 is in an off state.
　電源スイッチ１１４がオンされたとき、インバータ１２３の入力端子は電源スイッチ１１４を経由してＧＮＤに接続されるためハイレベルからローレベルに切り替わり、ＤＣＤＣコンバータ１２１のＥＮ端子はローレベルからハイレベルに切り替わる。それにより、ＤＣＤＣコンバータ１２１により発生された電源電圧ＶｄｄがＲＦＩＣ１２２に給電され、それによりＲＦＩＣ１２２の制御部は駆動し、電池形電源装置１００の状態はオフ状態から待機状態に遷移する。ＲＦＩＣ１２２が駆動されたのを契機に、制御部の制御に従って、無線通信部による送受信動作がオフからオンに切り替えられ、それにより電池形電源装置１００は待機状態から通信可能状態に遷移する。 When the power switch 114 is turned on, the input terminal of the inverter 123 is connected to GND via the power switch 114, so that it switches from high level to low level, and the EN terminal of the DCDC converter 121 switches from low level to high level. . Thereby, the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 is driven, and the state of the battery-type power supply device 100 is changed from the off state to the standby state. When the RFIC 122 is driven, the transmission / reception operation by the wireless communication unit is switched from OFF to ON according to the control of the control unit, whereby the battery-type power supply device 100 transitions from the standby state to the communicable state.
　電源スイッチ１１４がオフされたとき、再びインバータ１２３の入力端子はプルアップ抵抗１２４を介して内側正極端子１０５に接続されるためローレベルからハイレベルに切り替わり、それによりＲＦＩＣ１２２はオフされ、電池形電源装置１００の状態は通信可能状態からオフ状態に切り替わる。 When the power switch 114 is turned off, the input terminal of the inverter 123 is again connected to the inner positive terminal 105 through the pull-up resistor 124, so that it switches from the low level to the high level. The state of the apparatus 100 is switched from the communicable state to the off state.
　電池形電源装置１００が通信可能状態であるとき、電池形電源装置１００は、外部情報処理装置２００から受信した無線信号に従って、種々の処理を行うことができる。例えば無線通信部を介して、外部情報処理装置２００からモータ１１５のオンを指示するコード無線信号を受信したとき、制御信号発生部はローレベルのゲート制御信号を発生する。それにより出力トランジスタ１２０のゲート端子はローレベルになるため、出力トランジスタ１２０はオンし、モータ１１５が駆動する。このように、ユーザは、外部情報処理装置２００を操作することで、外部負荷装置１１１を自由なタイミングでオンすることができる。 When the battery-type power supply apparatus 100 is in a communicable state, the battery-type power supply apparatus 100 can perform various processes according to the radio signal received from the external information processing apparatus 200. For example, when a code wireless signal instructing to turn on the motor 115 is received from the external information processing apparatus 200 via the wireless communication unit, the control signal generating unit generates a low-level gate control signal. As a result, the gate terminal of the output transistor 120 becomes low level, so that the output transistor 120 is turned on and the motor 115 is driven. Thus, the user can turn on the external load device 111 at any timing by operating the external information processing device 200.
　図４で説明したように、第１実施形態に係る電池形電源装置１００によれば、外部負荷装置１１１の電源スイッチ１１４のオンに連動して電池形電源装置１００の状態をオフ状態から通信可能状態に切り替え、電源スイッチ１１４のオフに連動して、通信可能状態からオフ状態に切り替えることができる。これにより、電池形電源装置１００は、その状態をオフ状態と通信可能状態との間で切り替えるためのスイッチを装備する必要がなく、これは装置の小型化と部品コストの低減に寄与する。また、外部負荷装置１１１が初期状態であるとき、ＤＣＤＣコンバータ１２１とＲＦＩＣ１２２とが駆動していないため、不要な電力消費を低減することができる。 As described with reference to FIG. 4, according to the battery-type power supply device 100 according to the first embodiment, the state of the battery-type power supply device 100 can be communicated from the off state in conjunction with the power switch 114 of the external load device 111 being turned on. It is possible to switch from the communicable state to the off state in conjunction with the power switch 114 being switched off. Thereby, the battery-type power supply device 100 does not need to be equipped with a switch for switching the state between the off state and the communicable state, which contributes to downsizing of the device and reduction of component costs. Further, when the external load device 111 is in the initial state, the DCDC converter 121 and the RFIC 122 are not driven, so that unnecessary power consumption can be reduced.
　なお、第１実施形態に係る電池形電源装置１００では、インバータ１２３の出力信号をＤＣＤＣコンバータ１２１に入力しているが、インバータ１２３の出力信号をＲＦＩＣ１２２に入力する構成であってもよい。 In the battery-type power supply device 100 according to the first embodiment, the output signal of the inverter 123 is input to the DCDC converter 121, but the output signal of the inverter 123 may be input to the RFIC 122.
　図５は、第１実施形態に係る電池形電源装置１００の他の例を示す等価回路図である。インバータ１２３の出力端子はＲＦＩＣ１２２のＩＮＰＵＴ端子に接続される。ＲＦＩＣ１２２の入力段にインバータ１２３を配置することで、モータ１１５に発生する逆起電圧によるＲＦＩＣ１２２の破壊等を回避することができる。ＤＣＤＣコンバータ１２１のＥＮ端子は内側正極端子１０５に接続される。したがって、内蔵電池が電子収納部２に装着されている間、ＤＣＤＣコンバータ１２１はオンされるため、電池形電源装置１００は待機状態である。 FIG. 5 is an equivalent circuit diagram showing another example of the battery-type power supply device 100 according to the first embodiment. The output terminal of the inverter 123 is connected to the INPUT terminal of the RFIC 122. By disposing the inverter 123 at the input stage of the RFIC 122, destruction of the RFIC 122 due to a counter electromotive voltage generated in the motor 115 can be avoided. The EN terminal of the DCDC converter 121 is connected to the inner positive terminal 105. Accordingly, since the DCDC converter 121 is turned on while the built-in battery is mounted in the electronic storage unit 2, the battery-type power supply device 100 is in a standby state.
　ＲＦＩＣ１２２は、外側正極端子１０３の電圧レベルで判別される電源スイッチ１１４のオン／オフに従って、アンテナ１２７を介したＲＦ信号の送受信動作のオン／オフを切り替える。図４で説明したように、電源スイッチ１１４のオン／オフは、インバータ１２３の出力信号の電圧レベルで判別できる。電源スイッチ１１４がオンしているとき、インバータ１２３の出力信号はハイレベルであり、電源スイッチ１１４がオフしているとき、インバータ１２３の出力信号がローレベルである。したがって、ＩＮＰＵＴ端子がローレベルのとき、電源スイッチ１１４はオフされていると判別されるため、制御部の制御に従って無線通信部による送受信動作がオフされ、電池形電源装置１００の状態が通信可能状態から待機状態に切り替わる。ＩＮＰＵＴ端子がハイレベルのとき、電源スイッチ１１４はオンされていると判別されるため、制御部の制御に従って無線通信部による送受信動作がオンされ、電池形電源装置１００の状態は待機状態から通信可能状態に切り替わる。制御部による無線通信部の送受信動作のオン／オフの切り替えは、無線通信部の通信モジュールへの駆動電圧Ｖｄｄの給電を制御することで行われる。もちろん、制御部による無線通信部の送受信動作のオン／オフの切り替えは、通信モジュールが駆動している状態で、ソフトウェアで電波の出力を制御することで行われてもよい。 The RFIC 122 switches on / off of the transmission / reception operation of the RF signal via the antenna 127 according to on / off of the power switch 114 determined by the voltage level of the outer positive terminal 103. As described with reference to FIG. 4, the power switch 114 can be turned on / off based on the voltage level of the output signal of the inverter 123. When the power switch 114 is on, the output signal of the inverter 123 is at a high level, and when the power switch 114 is off, the output signal of the inverter 123 is at a low level. Therefore, when the INPUT terminal is at a low level, it is determined that the power switch 114 is turned off. Therefore, the transmission / reception operation by the wireless communication unit is turned off under the control of the control unit, and the state of the battery-type power supply device 100 is communicable. Switches from standby to standby. When the INPUT terminal is at a high level, it is determined that the power switch 114 is turned on. Therefore, the transmission / reception operation by the wireless communication unit is turned on under the control of the control unit, and the state of the battery-type power supply device 100 can be communicated from the standby state. Switch to state. Switching of the transmission / reception operation of the wireless communication unit by the control unit is performed by controlling the feeding of the drive voltage Vdd to the communication module of the wireless communication unit. Of course, on / off switching of the transmission / reception operation of the wireless communication unit by the control unit may be performed by controlling the output of radio waves with software while the communication module is driven.
　図５で説明したように、第１実施形態に係る電池形電源装置１００の他の例によれば、外部負荷装置１１１の電源スイッチ１１４のオンに連動して、電池形電源装置１００の状態を待機状態から通信可能状態に切り替え、電源スイッチ１１４のオフに連動して、通信可能状態から待機状態に切り替えることができる。これより、電池形電源装置１００は、その状態を待機状態と通信可能状態との間で切り替えるためのスイッチを装備する必要がなく、これは装置の小型化と部品コストの低減に寄与する。また、外部負荷装置１１１が初期状態であるとき、ＤＣＤＣコンバータ１２１とＲＦＩＣ１２２とが駆動していないため、不要な電力消費を低減することができる。 As described in FIG. 5, according to another example of the battery-type power supply device 100 according to the first embodiment, the state of the battery-type power supply device 100 is changed in conjunction with the power switch 114 of the external load device 111 being turned on. The standby state can be switched to the communicable state, and the communicable state can be switched to the standby state in conjunction with the power switch 114 being turned off. Thus, the battery-type power supply device 100 does not need to be equipped with a switch for switching the state between the standby state and the communicable state, which contributes to the downsizing of the device and the reduction of component costs. Further, when the external load device 111 is in the initial state, the DCDC converter 121 and the RFIC 122 are not driven, so that unnecessary power consumption can be reduced.
　また、図５のように回路を構成することで、内蔵電池が電池収納部１０２に装着されている間、電池形電源装置１００は待機状態である。制御部は、電源スイッチ１１４のオン／オフに連動して、無線通信部による送受信動作のオン／オフ以外の処理を実行してもよい。例えば、制御部は、電源スイッチ１１４のオン／オフに連動して、外部情報処理装置２００との間の通信間隔を変更させる。図６は、図５の電池形電源装置１００による通信間隔の変更処理の手順を示すフローチャートである。外部負荷装置１１１が初期状態であるとき、電池形電源装置１００は待機状態である。無線通信部は、制御部の制御に従って、外部情報処理装置２００と通信間隔Ｔ１で通信する（ステップＳ１１）。電源スイッチ１１４がオンされたとき（ステップＳ１２）、つまりＲＦＩＣ１２２のＩＮＰＵＴ端子がローレベルからハイレベルに切り替わったとき、無線通信部は、制御部の制御に従って、外部情報処理装置２００と通信間隔Ｔ１よりも短い通信間隔Ｔ２で通信する（ステップＳ１３）。通信間隔Ｔ１，Ｔ２はプリセットされていてもよいし、外部情報処理装置２００を介してユーザにより設定された値であってもよい。電源スイッチ１１４がオフされたとき（ステップＳ１４）、つまりＲＦＩＣ１２２のＩＮＰＵＴ端子がハイレベルからローレベルに切り替わったとき、処理ステップはステップＳ１１に戻り、無線通信部は、制御部の制御に従って、外部情報処理装置２００と通信間隔Ｔ１で通信する。 Further, by configuring the circuit as shown in FIG. 5, the battery-type power supply device 100 is in a standby state while the built-in battery is mounted in the battery storage unit 102. The control unit may execute processing other than on / off of the transmission / reception operation by the wireless communication unit in conjunction with the on / off of the power switch 114. For example, the control unit changes the communication interval with the external information processing apparatus 200 in conjunction with the on / off of the power switch 114. FIG. 6 is a flowchart showing a procedure of a communication interval changing process by the battery-type power supply device 100 of FIG. When the external load device 111 is in the initial state, the battery-type power supply device 100 is in a standby state. The wireless communication unit communicates with the external information processing apparatus 200 at the communication interval T1 according to the control of the control unit (step S11). When the power switch 114 is turned on (step S12), that is, when the INPUT terminal of the RFIC 122 is switched from the low level to the high level, the wireless communication unit is connected to the external information processing apparatus 200 and the communication interval T1 according to the control of the control unit. The communication is performed with a short communication interval T2 (step S13). The communication intervals T1 and T2 may be preset, or may be values set by the user via the external information processing apparatus 200. When the power switch 114 is turned off (step S14), that is, when the INPUT terminal of the RFIC 122 is switched from the high level to the low level, the processing step returns to step S11, and the wireless communication unit performs external information according to the control of the control unit. It communicates with the processing apparatus 200 at the communication interval T1.
　外部負荷装置１１１が待機状態であるとき、外部情報処理装置２００との間の通信間隔を短くすることで、外部情報処理装置２００からの指示に対する電池形電源装置１００の応答速度を向上し、また、外部情報処理装置２００との間の通信の接続性も向上することができる。また、外部負荷装置１１１がオフ状態（電源スイッチ１１４がオフ状態）であるとき、外部情報処理装置２００との間の通信間隔を長くすることで、不要な電力消費を低減することができる。 When the external load device 111 is in a standby state, the response interval of the battery-type power supply device 100 with respect to an instruction from the external information processing device 200 is improved by shortening the communication interval with the external information processing device 200, and Also, the connectivity of communication with the external information processing apparatus 200 can be improved. Further, when the external load device 111 is in the off state (the power switch 114 is in the off state), unnecessary power consumption can be reduced by increasing the communication interval with the external information processing device 200.

FIG. 7 is an equivalent circuit diagram illustrating an example of the battery-type power supply device 100 according to the second embodiment. One feature of the battery-type power supply device 100 according to the second embodiment is that an OR circuit 131 is arranged in front of the EN terminal of the DCDC converter 121. In the battery-type power supply device 100 according to the second embodiment, the protective diode 171 and the Zener diode 172 are connected in the same manner as the battery-type power supply device 100 according to the first embodiment, and thereby the same effects as in the first embodiment. Demonstrate.
　ＯＲ回路１３１は２つの入力端子と１つの出力端子とを有する。ＯＲ回路１３１は、その２つの入力端子のうち、少なくとも一方がハイレベルのとき、ハイレベルの信号を出力する。また、ＯＲ回路１３１は、その２つの入力端子の両方がローレベルのときローレベルの信号を出力する。ＯＲ回路１３１の出力端子はＤＣＤＣコンバータ１２１のＥＮ端子に接続される。ＯＲ回路１３１の出力端子とＤＣＤＣコンバータ１２１のＥＮ端子との間にはローパスフィルタ１３２が介在される。ローパスフィルタ１３２は、例えば抵抗とコンデンサとで構成される。ローパスフィルタ１３２は、遮断周波数より低い周波数の成分を通過させ、遮断周波数より高い周波数の成分を逓減させ、ノイズ等による瞬間的な信号の変動を抑制する。 The OR circuit 131 has two input terminals and one output terminal. The OR circuit 131 outputs a high level signal when at least one of the two input terminals is at a high level. The OR circuit 131 outputs a low level signal when both of its two input terminals are at a low level. The output terminal of the OR circuit 131 is connected to the EN terminal of the DCDC converter 121. A low pass filter 132 is interposed between the output terminal of the OR circuit 131 and the EN terminal of the DCDC converter 121. The low-pass filter 132 is composed of, for example, a resistor and a capacitor. The low-pass filter 132 allows a component having a frequency lower than the cutoff frequency to pass therethrough, gradually decreases a component having a frequency higher than the cutoff frequency, and suppresses instantaneous signal fluctuation due to noise or the like.
　ＯＲ回路１３１の一方の入力端子（第１入力端子）は、ＲＦＩＣ１２２のＯＵＴＰＵＴ端子に接続される。ＯＲ回路１３１の他方の入力端子（第２入力端子）は、検出トランジスタ１３０を経由して内側正極端子１０５に接続される。また、ＯＲ回路１３１の第１、第２入力端子はプルダウン抵抗１３６，１３５を介してＧＮＤに接続される。 One input terminal (first input terminal) of the OR circuit 131 is connected to the OUTPUT terminal of the RFIC 122. The other input terminal (second input terminal) of the OR circuit 131 is connected to the inner positive terminal 105 via the detection transistor 130. The first and second input terminals of the OR circuit 131 are connected to GND via pull-down resistors 136 and 135.
　ＲＦＩＣ１２２のＯＵＴＰＵＴ端子と出力トランジスタ１２０のゲート端子との間にはインバータ１３３が介在される。インバータ１３３の出力は出力トランジスタ１２０のゲートに入力される。 An inverter 133 is interposed between the OUTPUT terminal of the RFIC 122 and the gate terminal of the output transistor 120. The output of the inverter 133 is input to the gate of the output transistor 120.
　検出トランジスタ１３０は、典型的にはＰチャンネルＭＯＳＦＥＴであり、電源スイッチ１１４のオン／オフを検出する。検出トランジスタ１３０のドレイン端子はＯＲ回路１３１の第２入力端子に接続され、ソース端子は内側正極端子１０５に接続され、ゲート端子は外側正極端子１０３に接続される。第１実施形態と同様に、プルアップ抵抗（検出抵抗）１２４は、内側正極端子１０５と外側正極端子１０３との間に出力トランジスタ１２０と並列に配置される。それにより、電源スイッチ１１４のオン／オフに連動して、外側正極端子１０３の信号レベルをローレベルとハイレベルとの間で切り替えることができる。検出トランジスタ１３０のゲート端子を外側正極端子１０３に接続することで、電源スイッチ１１４のオン／オフに連動して検出トランジスタ１３０をオン／オフさせることができる。 The detection transistor 130 is typically a P-channel MOSFET, and detects ON / OFF of the power switch 114. The drain terminal of the detection transistor 130 is connected to the second input terminal of the OR circuit 131, the source terminal is connected to the inner positive terminal 105, and the gate terminal is connected to the outer positive terminal 103. Similar to the first embodiment, the pull-up resistor (detection resistor) 124 is arranged in parallel with the output transistor 120 between the inner positive terminal 105 and the outer positive terminal 103. Thereby, the signal level of the outer positive terminal 103 can be switched between the low level and the high level in conjunction with the on / off of the power switch 114. By connecting the gate terminal of the detection transistor 130 to the outer positive terminal 103, the detection transistor 130 can be turned on / off in conjunction with the on / off of the power switch 114.
　制御信号発生部は、制御部の制御に従って、受信したモータ出力指示値に応じたゲート制御信号を発生する。ここでは、ゲート制御信号は、ＰＷＭ（パルス幅信号変調）信号で提供される。例えば、モータ出力指示値が０％の場合において、制御信号発生部はデューティー比０％（ローレベルのみ）のＰＷＭ信号を発生する。モータ出力指示値が１００％の場合において、制御信号発生部はデューティー比１００％（ハイレベルのみ）のＰＷＭ信号を発生する。モータ出力指示値が５０％の場合において、制御信号発生部はデューティー比５０％（ローレベルとハイレベルの比が半分）の信号を発生する。制御信号発生部により発生されたＰＷＭ信号は出力トランジスタ１２０にゲート制御信号として入力される。 The control signal generation unit generates a gate control signal corresponding to the received motor output instruction value according to the control of the control unit. Here, the gate control signal is provided as a PWM (pulse width signal modulation) signal. For example, when the motor output instruction value is 0%, the control signal generator generates a PWM signal with a duty ratio of 0% (only low level). When the motor output instruction value is 100%, the control signal generator generates a PWM signal with a duty ratio of 100% (only high level). When the motor output instruction value is 50%, the control signal generator generates a signal with a duty ratio of 50% (the ratio between the low level and the high level is half). The PWM signal generated by the control signal generator is input to the output transistor 120 as a gate control signal.
　ＰＷＭ信号がハイレベル（ゲート端子がローレベル）のとき、出力トランジスタ１２０はオン状態である。そのため、外部負荷装置１１１の回路は導通され、モータ１１５は駆動する。ＰＷＭ信号（ゲート制御信号）がローレベル（ゲート端子がハイレベル）のとき、出力トランジスタ１２０はオフ状態である。そのため、外部負荷装置１１１の回路は遮断され、モータ１１５は駆動しない。ＰＷＭ信号がゲート端子に入力されている間、モータ１１５は回転開始と回転停止とを所定の周期で繰り返す。出力トランジスタ１２０がオンからオフに切り替わると、モータ１１５はそのコイル特性により、徐々に回転が落ちていくこととなるが、出力トランジスタ１２０がオンからオフに切り替わると再度回転が速くなる。この特性を使って、ＰＷＭ制御によりモータ１１５を任意の回転数で回転させることができる。 When the PWM signal is at a high level (the gate terminal is at a low level), the output transistor 120 is on. Therefore, the circuit of the external load device 111 is conducted and the motor 115 is driven. When the PWM signal (gate control signal) is at a low level (the gate terminal is at a high level), the output transistor 120 is in an off state. Therefore, the circuit of the external load device 111 is cut off and the motor 115 is not driven. While the PWM signal is input to the gate terminal, the motor 115 repeats the rotation start and the rotation stop at a predetermined cycle. When the output transistor 120 is switched from on to off, the motor 115 gradually rotates due to its coil characteristics. However, when the output transistor 120 is switched from on to off, the rotation becomes faster again. Using this characteristic, the motor 115 can be rotated at an arbitrary rotational speed by PWM control.
　（動作説明）　
　第２実施形態に係る電池形電源装置１００の一つの特徴は、ＤＣＤＣコンバータ１２１の前段にＯＲ回路１３１を配置した点にある。ＯＲ回路１３１は、ＲＦＩＣ１２２から出力されるゲート制御信号と検出トランジスタ１３０の検出信号との入力を受け、論理和の演算結果として、ＤＣＤＣコンバータ１２１にハイレベル又はローレベルの信号を出力する。それにより、電源スイッチ１１４がオン状態であれば、電池形電源装置１００が通信可能状態からオフ状態又は待機状態に切り替わるのを回避することができる。 (Description of operation)
One feature of the battery-type power supply device 100 according to the second embodiment is that an OR circuit 131 is arranged in the previous stage of the DCDC converter 121. The OR circuit 131 receives the gate control signal output from the RFIC 122 and the detection signal of the detection transistor 130, and outputs a high-level or low-level signal to the DCDC converter 121 as a logical sum operation result. Thereby, if the power switch 114 is in the on state, the battery-type power supply device 100 can be prevented from switching from the communicable state to the off state or the standby state.
　具体的には、外部負荷装置１１１が初期状態であるとき、検出トランジスタ１３０もＲＦＩＣ１２２もオフされているため、ＯＲ回路１３１の第１、第２入力端子はそれぞれプルダウン抵抗１３６，１３５を経由してＧＮＤに接続されるため、ローレベルである。したがって、ＤＣＤＣコンバータ１２１により発生された電源電圧ＶｄｄがＲＦＩＣ１２２に給電されない。そのため、電池形電源装置１００はオフ状態である。 Specifically, when the external load device 111 is in the initial state, both the detection transistor 130 and the RFIC 122 are turned off, so that the first and second input terminals of the OR circuit 131 go through the pull-down resistors 136 and 135, respectively. Since it is connected to GND, it is at a low level. Therefore, the power supply voltage Vdd generated by the DCDC converter 121 is not supplied to the RFIC 122. Therefore, the battery-type power supply device 100 is in an off state.
　電源スイッチ１１４がオンされたとき、検出トランジスタ１３０のゲート端子は、電源スイッチ１１４を経由してＧＮＤに接続されるためハイレベルからローレベルに切り替わる。ＯＲ回路１３１の第２入力端子は検出トランジスタ１３０を経由して内側正極端子１０５に接続されローレベルからハイレベルに切り替わり、それによりＯＲ回路１３１はハイレベルの信号を出力する。ＤＣＤＣコンバータ１２１のＥＮ端子がローレベルからハイレベルに切り替わり、ＤＣＤＣコンバータ１２１により発生された電源電圧ＶｄｄがＲＦＩＣ１２２に給電され、それによりＲＦＩＣ１２２の制御部は駆動し、電池形電源装置１００の状態はオフ状態から待機状態に切り替わる。ＲＦＩＣ１２２の制御部が駆動されたのを契機に、制御部の制御に従って、無線通信部による送受信動作がオフからオンに切り替えられ、電池形電源装置１００の状態は待機状態から通信可能状態に切り替わる。出力トランジスタ１２０は、外部情報処理装置２００からのモータ出力指示に応じたＰＷＭ信号に従ってその電源出力が調整される。 When the power switch 114 is turned on, the gate terminal of the detection transistor 130 is connected to GND via the power switch 114, so that the high level is switched to the low level. The second input terminal of the OR circuit 131 is connected to the inner positive terminal 105 via the detection transistor 130 and is switched from the low level to the high level, whereby the OR circuit 131 outputs a high level signal. The EN terminal of the DCDC converter 121 is switched from the low level to the high level, and the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 is driven and the state of the battery-type power supply device 100 is off. Switch from state to standby state. When the control unit of the RFIC 122 is driven, the transmission / reception operation by the wireless communication unit is switched from OFF to ON according to the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state. The power output of the output transistor 120 is adjusted according to a PWM signal according to a motor output instruction from the external information processing apparatus 200.
　電源スイッチ１１４がオンされた状態で、出力トランジスタ１２０がオフされたとき（出力トランジスタ１２０のゲート端子がハイレベルであるとき）、検出トランジスタ１３０のゲート端子は電源スイッチ１１４を介してＧＮＤに接続されるためローレベルであり、それにより検出トランジスタ１３０はオンされる。検出トランジスタ１３０がオンされることで、ＯＲ回路１３１の第１入力端子は検出トランジスタ１３０を介して内側正極端子１０５に接続されるためハイレベルであり、それによりＯＲ回路１３１はハイレベルの信号をＤＣＤＣコンバータ１２１に出力する。 When the output transistor 120 is turned off with the power switch 114 turned on (when the gate terminal of the output transistor 120 is at high level), the gate terminal of the detection transistor 130 is connected to GND via the power switch 114. Therefore, the detection transistor 130 is turned on. When the detection transistor 130 is turned on, the first input terminal of the OR circuit 131 is connected to the inner positive electrode terminal 105 via the detection transistor 130, so that the OR circuit 131 outputs a high level signal. It outputs to the DCDC converter 121.
　電源スイッチ１１４がオンされた状態で、出力トランジスタ１２０がオンされたとき（出力トランジスタ１２０のゲート端子がローレベルであるとき）、検出トランジスタ１３０のゲート端子は出力トランジスタ１２０を介して内側正極端子１０５に接続されるためハイレベルであり、それにより検出トランジスタ１３０はオフされる。ＯＲ回路１３１の第１入力端子は、プルダウン抵抗１３６を介してＧＮＤに接続されるためローレベルである。一方で、出力トランジスタ１２０がオンされているとき、ＯＵＴＰＵＴ端子から出力されているゲート制御信号はハイレベルである。したがって、ＯＲ回路１３１の第２入力端子はＯＵＴＰＵＴ端子に接続されるためハイレベルであり、それによりＯＲ回路１３１はハイレベルの信号をＤＣＤＣコンバータ１２１に出力する。 When the output transistor 120 is turned on with the power switch 114 turned on (when the gate terminal of the output transistor 120 is at a low level), the gate terminal of the detection transistor 130 is connected to the inner positive terminal 105 via the output transistor 120. Therefore, the detection transistor 130 is turned off. Since the first input terminal of the OR circuit 131 is connected to GND through the pull-down resistor 136, it is at a low level. On the other hand, when the output transistor 120 is turned on, the gate control signal output from the OUTPUT terminal is at a high level. Therefore, since the second input terminal of the OR circuit 131 is connected to the OUTPUT terminal, it is at a high level, whereby the OR circuit 131 outputs a high level signal to the DCDC converter 121.
　したがって、ゲート制御信号により出力トランジスタ１２０がオフされている間、ＯＲ回路１３１の第１入力端子がハイレベル、第２入力端子がローレベルであるため、ＯＲ回路１３１はハイレベルの信号を出力する。一方、出力トランジスタ１２０がオンされている間、ＯＲ回路１３１の第１入力端子がローレベル、第２入力端子がハイレベルであるため、ＯＲ回路１３１はハイレベルの信号を出力する。 Therefore, while the output transistor 120 is turned off by the gate control signal, the OR circuit 131 outputs a high level signal because the first input terminal of the OR circuit 131 is at the high level and the second input terminal is at the low level. . On the other hand, while the output transistor 120 is on, the OR circuit 131 outputs a high level signal because the first input terminal of the OR circuit 131 is at a low level and the second input terminal is at a high level.
　このように、電源スイッチ１１４がオンされていれば、出力トランジスタ１２０がゲート制御信号によりオン／オフされても、ＯＲ回路１３１はオン状態を維持することができる。それにより、ゲート制御信号にＰＷＭ信号を使用した場合でも、電池形電源装置１００の状態を通信可能状態で維持することができる。ＰＷＭ信号の使用が可能となることで、電源出力を０％から１００％の範囲で自在に調整できる電源装置を提供することができる。それにより、例えば第２実施形態に係る電池形電源装置１００を電池ボックス１１２に装着するだけで、元々、電源出力を調整する手段を装備していない外部負荷装置１１１に電源出力を調整する手段を与えることができる。ユーザは、外部情報処理装置２００を操作して、例えば電池形電源装置１００を装着する電動玩具の動作速度を自由に変更することができる。 Thus, if the power switch 114 is turned on, the OR circuit 131 can maintain the on state even if the output transistor 120 is turned on / off by the gate control signal. Thereby, even when a PWM signal is used as the gate control signal, the state of the battery-type power supply device 100 can be maintained in a communicable state. Since the PWM signal can be used, it is possible to provide a power supply apparatus that can freely adjust the power supply output in the range of 0% to 100%. Thus, for example, by simply mounting the battery-type power supply device 100 according to the second embodiment in the battery box 112, means for adjusting the power output to the external load device 111 that is not originally equipped with means for adjusting the power output. Can be given. The user can operate the external information processing apparatus 200 to freely change the operation speed of the electric toy that is mounted with the battery-type power supply apparatus 100, for example.
　なお、第２実施形態では、ＯＲ回路１３１の出力信号をＤＣＤＣコンバータ１２１に入力する構成としたが、ＯＲ回路１３１の出力信号をＲＦＩＣ１２２のＩＮＰＵＴ端子に入力する構成にし、ＩＮＰＵＴ端子の信号レベルに従って、制御部により無線通信部による送受信動作のオン／オフが切り替えるようにしてもよい。
（第３実施形態）　
　第１、第２実施形態では、出力トランジスタ１２０にＰチャンネルＭＯＳＦＥＴを使用した場合の回路例について説明したが、出力トランジスタ１２０として、ＮチャンネルＭＯＳＦＥＴを使用してもよい。ＮチャンネルＭＯＳＦＥＴは、ＰチャンネルＭＯＳＦＥＴに比べて安価なものがあり、ＮチャンネルＭＯＳＦＥＴを使用することで、電池形電源装置１００の部品コストを低減することができる。また、ＮチャンネルＭＯＳＦＥＴは、ＰチャンネルＭＯＳＦＥＴに比べて耐圧が高いものがあり、ＮチャンネルＭＯＳＦＥＴを使用することで、電池形電源装置１００に対して直列に接続できる外部電池の数を増やすことができる。これは、電池形電源装置１００を使用できる外部負荷装置１１１の範囲の拡大が期待できる。なお、出力トランジスタ１２０は、バイポーラトランジスタであってもよく、その場合ゲート制御信号はベース制御信号と読み替えられる。 In the second embodiment, the output signal of the OR circuit 131 is input to the DCDC converter 121. However, the output signal of the OR circuit 131 is input to the INPUT terminal of the RFIC 122, and according to the signal level of the INPUT terminal, You may make it switch on / off of the transmission / reception operation | movement by a radio | wireless communication part by a control part.
(Third embodiment)
In the first and second embodiments, a circuit example in which a P-channel MOSFET is used as the output transistor 120 has been described. However, an N-channel MOSFET may be used as the output transistor 120. Some N-channel MOSFETs are less expensive than P-channel MOSFETs, and the use of an N-channel MOSFET can reduce the component cost of the battery-type power supply device 100. Some N-channel MOSFETs have a higher withstand voltage than P-channel MOSFETs, and the use of N-channel MOSFETs can increase the number of external batteries that can be connected in series to the battery-type power supply device 100. . This can be expected to expand the range of the external load device 111 in which the battery-type power supply device 100 can be used.

　（動作説明）　
　外部負荷装置１１１が初期状態（電源スイッチ１１４がオフ状態）であるとき、第２検出トランジスタ１４１は、そのゲート端子がプルダウン抵抗１４３を介してＧＮＤに接続されるためローレベルであり、オフ状態である。第１検出トランジスタ１３０は、そのゲート端子がプルアップ抵抗１３４を介して内側正極端子１０５に接続されるためハイレベルであり、オフ状態である。外部負荷装置１１１が初期状態でＲＦＩＣ１２２は駆動していないため、ゲート制御信号は出力されない。したがって、ＯＲ回路１３１は、その第１、第２入力端子がそれぞれプルダウン抵抗１３６，１３５を経由してＧＮＤに接続されるためローレベルであるため、ローレベルの信号を出力する。 (Description of operation)
When the external load device 111 is in an initial state (the power switch 114 is in an off state), the second detection transistor 141 is at a low level because its gate terminal is connected to GND via the pull-down resistor 143, and in the off state. is there. Since the gate terminal of the first detection transistor 130 is connected to the inner positive terminal 105 via the pull-up resistor 134, the first detection transistor 130 is at a high level and is in an off state. Since the external load device 111 is in an initial state and the RFIC 122 is not driven, no gate control signal is output. Therefore, the OR circuit 131 outputs a low-level signal because its first and second input terminals are connected to GND via the pull-down resistors 136 and 135, respectively, and thus are at a low level.
　電源スイッチ１１４がオンされたとき、第２検出トランジスタ１４１は、そのゲート端子が外側負極端子１０４、モータ１１５、電源スイッチ１１４、外側正極端子１０３を経由して内側正極端子１０５に接続されハイレベルであるため、オンされる。第１検出トランジスタ１３０は、そのゲート端子が第２検出トランジスタ１４１を経由してＧＮＤに接続されローレベルであるため、オンされる。ＯＲ回路１３１の第２入力端子は第１検出トランジスタ１３０を経由して内側正極端子１０５に接続されローレベルからハイレベルに切り替わり、それによりＯＲ回路１３１はハイレベルの信号を出力する。ＤＣＤＣコンバータ１２１のＥＮ端子がローレベルからハイレベルに切り替わり、ＤＣＤＣコンバータ１２１により発生された電源電圧ＶｄｄがＲＦＩＣ１２２に給電され、それによりＲＦＩＣ１２２の制御部は駆動し、電池形電源装置１００の状態はオフ状態から待機状態に切り替わる。ＲＦＩＣ１２２の制御部が駆動されたのを契機に、制御部の制御に従って、無線通信部による送受信動作がオフからオンに切り替えられ、電池形電源装置１００の状態は待機状態から通信可能状態に切り替わる。出力トランジスタ１２０は、外部情報処理装置２００からのモータ出力指示に応じたＰＷＭ信号に従ってその電源出力が調整される。 When the power switch 114 is turned on, the gate terminal of the second detection transistor 141 is connected to the inner positive terminal 105 via the outer negative terminal 104, the motor 115, the power switch 114, and the outer positive terminal 103. Because there is, it is turned on. The first detection transistor 130 is turned on because its gate terminal is connected to GND via the second detection transistor 141 and is at a low level. The second input terminal of the OR circuit 131 is connected to the inner positive terminal 105 via the first detection transistor 130 and is switched from the low level to the high level, whereby the OR circuit 131 outputs a high level signal. The EN terminal of the DCDC converter 121 is switched from the low level to the high level, and the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 is driven and the state of the battery-type power supply device 100 is off. Switch from state to standby state. When the control unit of the RFIC 122 is driven, the transmission / reception operation by the wireless communication unit is switched from OFF to ON according to the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state. The power output of the output transistor 120 is adjusted according to a PWM signal according to a motor output instruction from the external information processing apparatus 200.
　以上説明した第３実施形態に係る電池形電源装置１００によれば、電源スイッチ１１４のオン／オフに連動して、その状態をオフ状態と通信可能状態との間で切り替えることができる。また、電源スイッチ１１４がオンされていれば、出力トランジスタ１２０がゲート制御信号によりオン／オフされても、ＯＲ回路１３１はオン状態を維持することができる。それにより、ゲート制御信号にＰＷＭ信号を使用した場合でも、電池形電源装置１００の状態を通信可能状態で維持することができる。つまり、出力トランジスタ１２０にＮチャンネルＭＯＳＦＥＴを用いた場合であっても、出力トランジスタ１２０にＰチャンネルＭＯＳＦＥＴを用いた第２実施形態に係る電池形電源装置１００と同様に動作させることができ、同様の効果を得られる。 According to the battery-type power supply device 100 according to the third embodiment described above, the state can be switched between the off state and the communicable state in conjunction with the on / off of the power switch 114. Further, if the power switch 114 is turned on, the OR circuit 131 can be kept on even when the output transistor 120 is turned on / off by the gate control signal. Thereby, even when a PWM signal is used as the gate control signal, the state of the battery-type power supply device 100 can be maintained in a communicable state. That is, even when an N-channel MOSFET is used for the output transistor 120, it can be operated in the same manner as the battery-type power supply device 100 according to the second embodiment using a P-channel MOSFET for the output transistor 120. The effect can be obtained.

In the battery-type power supply device 100 according to the second embodiment, an OR circuit 131 is disposed in front of the EN terminal of the DCDC converter 121. The OR circuit 131 outputs the PWM signal output from the RFIC 122 and the detection signal output from the detection transistor 130. If the power switch 114 is in the ON state even when the PWM signal is used as the gate control signal of the output transistor 120, the battery-type power supply device 100 can be maintained in a communicable state. . In the battery-type power supply device 100 according to the fourth embodiment, the processing performed by the OR circuit 131 of the second embodiment is performed inside the RFIC 122.

　（動作説明）　
　図１１は、図１０のＲＦＩＣ１２２によるＰＷＭ制御中の各端子の入出力の変化を示すタイミングチャートである。図１２は、図１０のＲＦＩＣ１２２による送受信動作のオン／オフの切り替え処理の手順を示すフローチャートである。制御部は、制御信号発生部により発生され、ＯＵＴＰＵＴ端子から出力されたゲート制御信号とＩＮＰＵＴ端子に入力される信号との論理和に従って、無線通信部による送受信動作のオン／オフを制御する。具体的には、制御部は、ＯＵＴＰＵＴ端子から出力するゲート制御信号とＩＮＰＵＴ端子に入力される信号との論理和がハイレベルのとき送受信動作をオンし、ローレベルのときオフする。 (Description of operation)
FIG. 11 is a timing chart showing changes in input / output of each terminal during PWM control by the RFIC 122 of FIG. FIG. 12 is a flowchart showing the procedure of the on / off switching process of the transmission / reception operation by the RFIC 122 of FIG. The control unit controls on / off of the transmission / reception operation by the wireless communication unit according to the logical sum of the gate control signal generated by the control signal generation unit and output from the OUTPUT terminal and the signal input to the INPUT terminal. Specifically, the control unit turns on the transmission / reception operation when the logical sum of the gate control signal output from the OUTPUT terminal and the signal input to the INPUT terminal is high level, and turns off when the logical sum is low level.
　図１２に示すように、外部負荷装置１１１が初期状態（電源スイッチ１１４がオフ状態）であるとき、ＲＦＩＣ１２２のＩＮＰＵＴ端子はローレベル、ＯＵＴＰＵＴ端子はローレベルである（ステップＳ２１）。したがって、これら２つの端子の信号レベルの論理和はローレベルであるため、無線通信部による送受信動作はオンされていない。したがって、電池形電源装置１００は、送受信動作がオフされた待機状態である。ＩＮＰＵＴ端子がローレベルからハイレベルに切り替わったとき、つまり電源スイッチ１１４がオンされたとき（ステップＳ２２）、これら２つの端子の信号レベルの論理和はローレベルからハイレベルに切り替わる。それにより、制御部の制御に従って無線通信部による送受信動作がオンされ、電池形電源装置１００の状態は待機状態から通信可能状態に切り替わる（ステップＳ２３）。 As shown in FIG. 12, when the external load device 111 is in the initial state (the power switch 114 is off), the INPUT terminal of the RFIC 122 is at the low level and the OUTPUT terminal is at the low level (step S21). Therefore, since the logical sum of the signal levels of these two terminals is low level, the transmission / reception operation by the wireless communication unit is not turned on. Therefore, the battery-type power supply device 100 is in a standby state in which the transmission / reception operation is turned off. When the INPUT terminal is switched from the low level to the high level, that is, when the power switch 114 is turned on (step S22), the logical sum of the signal levels of these two terminals is switched from the low level to the high level. Thereby, the transmission / reception operation by the wireless communication unit is turned on under the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state (step S23).
　ＩＮＰＵＴ端子がハイレベルのとき（ステップＳ２４のＹｅｓ）、制御部の制御に従って無線通信部による送受信動作がオン状態で維持され、それにより電池形電源装置１００は通信可能状態で維持される（ステップＳ２６）。ＩＮＰＵＴ端子がローレベルのとき、制御部はＯＵＴＰＵＴ端子の信号レベルに従って、送受信動作のオン／オフを切り替える。ＩＮＰＵＴ端子がローレベル、ＯＵＴＰＵＴ端子がハイレベルのとき、ゲート制御信号のハイレベルにより出力トランジスタ１２０がオンされ、モータ１１５が駆動している状態である。したがって、電池形電源装置１００は通信可能状態で維持すべきである。そのため、ＩＮＰＵＴ端子がローレベル（ステップＳ２４のＮｏ）、ＯＵＴＰＵＴ端子がハイレベルのとき（ステップＳ２５のＹｅｓ）、制御部の制御に従って無線通信部による送受信動作がオン状態で維持され、それにより電池形電源装置１００は通信可能状態で維持される（ステップＳ２６）。ＩＮＰＵＴ端子がローレベル、ＯＵＴＰＵＴ端子がローレベルのとき（または開放されているとき）は、電源スイッチ１１４がオフされている状態であり、不要な電力消費の低減の観点から、電池形電源装置１００を通信可能状態から待機状態に切り替えるべきである。したがって、ＩＮＰＵＴ端子がローレベル（ステップＳ２４のＮｏ）、ＯＵＴＰＵＴ端子がローレベルのとき（ステップＳ２５のＮｏ）、制御部の制御に従って無線通信部による送受信動作がオンからオフに切り替えられ、それにより電池形電源装置１００の状態は通信可能状態から待機状態に切り替わる（ステップＳ２７）。 When the INPUT terminal is at a high level (Yes in step S24), the transmission / reception operation by the wireless communication unit is maintained in the on state according to the control of the control unit, whereby the battery-type power supply device 100 is maintained in the communicable state (step S26). ). When the INPUT terminal is at the low level, the control unit switches on / off of the transmission / reception operation according to the signal level of the OUTPUT terminal. When the INPUT terminal is at the low level and the OUTPUT terminal is at the high level, the output transistor 120 is turned on by the high level of the gate control signal, and the motor 115 is driven. Therefore, the battery-type power supply device 100 should be maintained in a communicable state. Therefore, when the INPUT terminal is at a low level (No in step S24) and the OUTPUT terminal is at a high level (Yes in step S25), the transmission / reception operation by the wireless communication unit is maintained in an on state according to the control of the control unit. The power supply apparatus 100 is maintained in a communicable state (step S26). When the INPUT terminal is at a low level and the OUTPUT terminal is at a low level (or open), the power switch 114 is turned off. From the viewpoint of reducing unnecessary power consumption, the battery-type power supply device 100 Should be switched from the communicable state to the standby state. Therefore, when the INPUT terminal is at a low level (No in step S24) and the OUTPUT terminal is at a low level (No in step S25), the transmission / reception operation by the wireless communication unit is switched from on to off according to the control of the control unit. The state of the power supply apparatus 100 is switched from the communicable state to the standby state (step S27).
　以上説明した制御部による送受信動作のオン／オフの切り替え制御により、図１１に示すように、電源スイッチ１１４がオフされている間、送受信動作をオフし、電源スイッチ１１４がオンされている間、送受信動作をオンすることができる。したがって、第４実施形態に係る電池形電源装置１００は、第２実施形態のようにＯＲ回路１３１を配置することなく、第２実施形態に係る電池形電源装置１００に比べて部品点数を少なくした状態で、ゲート制御信号としてＰＷＭ信号を使用することができる。なお、ここでは電源スイッチ１１４のオン／オフに連動して電池形電源装置１００の通信機能をオン／オフするとしたが、図５で説明したように、電源スイッチ１１４のオン／オフに連動して電池形電源装置１００の通信間隔を変更させてもよい。例えば、電源スイッチ１１４がオン状態であるとき通信間隔を短くすることで、外部情報処理装置２００からの指示に対する電池形電源装置１００の応答速度を向上し、また、外部情報処理装置２００との間の通信の接続性も向上することができる。また、電源スイッチ１１４がオフされた状態で、外部情報処理装置２００との間の通信間隔を長くすることで、不要な電力消費を低減することができる。 As shown in FIG. 11, the transmission / reception operation is turned off and the power switch 114 is turned on while the power switch 114 is turned off, as shown in FIG. The transmission / reception operation can be turned on. Therefore, the battery-type power supply device 100 according to the fourth embodiment reduces the number of parts compared to the battery-type power supply device 100 according to the second embodiment without arranging the OR circuit 131 as in the second embodiment. In the state, a PWM signal can be used as a gate control signal. Here, the communication function of the battery-type power supply device 100 is turned on / off in conjunction with the on / off of the power switch 114. However, as described with reference to FIG. The communication interval of the battery-type power supply device 100 may be changed. For example, by shortening the communication interval when the power switch 114 is in the ON state, the response speed of the battery-type power supply device 100 with respect to an instruction from the external information processing device 200 is improved, and between the external information processing device 200 The communication connectivity can be improved. Further, unnecessary power consumption can be reduced by increasing the communication interval with the external information processing apparatus 200 in a state where the power switch 114 is turned off.
　また、制御部による送受信動作のオン／オフの切り替えを制御する方法は上記に限定されない。例えば、制御部は、ＯＵＴＰＵＴ端子からゲート制御信号を出力している間、無線通信部による送受信動作のオン／オフ制御を行わないようにしてもよい。これにより、ゲート制御信号により出力トランジスタ１２０がオン／オフされ、ＩＮＰＵＴ端子の入力信号の電圧レベルが変化しても、電池形電源装置１００を、ＯＵＴＰＵＴ端子からゲート制御信号が出力される直前の状態、つまり通信可能状態で維持することができる。 Further, the method for controlling the on / off switching of the transmission / reception operation by the control unit is not limited to the above. For example, the control unit may not perform the on / off control of the transmission / reception operation by the wireless communication unit while outputting the gate control signal from the OUTPUT terminal. As a result, even when the output transistor 120 is turned on / off by the gate control signal and the voltage level of the input signal at the INPUT terminal changes, the battery-type power supply device 100 is in a state immediately before the gate control signal is output from the OUTPUT terminal. That is, the communication can be maintained.

　電源スイッチ１１４がオフされている状態で、第１、第３出力トランジスタ１６１、１６３は、それらのソース端子がハイレベル、それらのゲート端子がプルアップ抵抗１５１，１５３を介して内側正極端子１０５に接続されるためハイレベルであるためオフ状態である。第２出力トランジスタ１６２は、そのソース端子がローレベル、ゲート端子がプルダウン抵抗１５２を介して内側負極端子１０６に接続されローレベルであるためオフ状態である。第４出力トランジスタ１６４は、そのソース端子がローレベル、ゲート端子がプルアップ抵抗１５４を介して内側正極端子１０５に接続されるためハイレベルでありオン状態である。検出トランジスタ１３０は、そのソース端子がハイレベル、ゲート端子がプルアップ抵抗１３４を介して内側正極端子１０５に接続されるためハイレベルでありオフ状態である。 (Circuit operation)
FIG. 14 is a diagram showing the terminal voltage of each transistor that varies with the on / off of the power switch 114 of FIG.
With the power switch 114 turned off, the first and third output transistors 161 and 163 have their source terminals at the high level and their gate terminals connected to the inner positive terminal 105 via the pull-up resistors 151 and 153. Since it is connected and is at a high level, it is in an off state. The second output transistor 162 is in an off state because its source terminal is low level and its gate terminal is connected to the inner negative terminal 106 via the pull-down resistor 152 and is at low level. The fourth output transistor 164 is at a high level and is in an on state because its source terminal is connected to the low level and its gate terminal is connected to the inner positive terminal 105 via the pull-up resistor 154. The detection transistor 130 is at a high level and has an off state because its source terminal is connected to the inner positive electrode terminal 105 via a pull-up resistor 134 and its gate terminal is high level.
　電源スイッチ１１４がオンされたとき、検出トランジスタ１３０のゲート端子は第４出力トランジスタ１６４を介して内側負極端子１０６に接続されるためハイレベルからローレベルに切り替わり、それにより検出トランジスタ１３０はオンされる。検出トランジスタ１３０がオンされることで、ＯＲ回路１３１の第２入力端子はハイレベルになり、ＤＣＤＣコンバータ１２１からＲＦＩＣ１２２に駆動電圧Ｖｄｄが給電され、ＲＦＩＣ１２２が駆動され、電池形電源装置１００の状態はオフ状態から通信可能状態に切り替わる。 When the power switch 114 is turned on, the gate terminal of the detection transistor 130 is connected to the inner negative terminal 106 via the fourth output transistor 164, so that the detection transistor 130 is turned on. . When the detection transistor 130 is turned on, the second input terminal of the OR circuit 131 becomes high level, the drive voltage Vdd is supplied from the DCDC converter 121 to the RFIC 122, the RFIC 122 is driven, and the state of the battery-type power supply device 100 is Switch from off to communicable state.
　第５実施形態に係る電池形電源装置１００は、無線通信部を介して外部情報処理装置２００からモータ回転方向の切替指示とに関するコード無線信号を受信する。モータを正回転させるためのコード無線信号を受信したとき、制御信号発生部により発生されたゲート制御信号は、制御部の制御に従って、ＯＵＴＰＵＴ１端子から出力される。一方、モータを逆回転させるためのコード無線信号を受信したとき、制御信号発生部により発生されたゲート制御信号は、制御部の制御に従って、ＯＵＴＰＵＴ２端子から出力される。ゲート制御信号がＯＵＴＰＵＴ１端子から出力されたとき、第１、第４出力トランジスタ１６１、１６４が互いに同時にオン／オフされる。同様に、ゲート制御信号がＯＵＴＰＵＴ２端子から出力されたとき、第２、第３出力トランジスタ１６２、１６３は互いに同時にオン／オフされる。なお、ＯＵＴＰＵＴ１端子とＯＵＴＰＵＴ端子２とから同時にゲート制御信号が出力されないように設定されている。それにより、第１、第４出力トランジスタ１６４がオンされているときに、第２、第３出力トランジスタ１６３がオンされることはなく、回路の誤動作、回路ショート等を回避できる。 The battery-type power supply apparatus 100 according to the fifth embodiment receives a code wireless signal related to a motor rotation direction switching instruction from the external information processing apparatus 200 via a wireless communication unit. When a code wireless signal for forward rotation of the motor is received, the gate control signal generated by the control signal generator is output from the OUTPUT1 terminal according to the control of the controller. On the other hand, when the code wireless signal for rotating the motor in the reverse direction is received, the gate control signal generated by the control signal generator is output from the OUTPUT2 terminal according to the control of the controller. When the gate control signal is output from the OUTPUT1 terminal, the first and fourth output transistors 161 and 164 are turned on / off simultaneously. Similarly, when the gate control signal is output from the OUTPUT2 terminal, the second and third output transistors 162 and 163 are simultaneously turned on / off. The gate control signal is set so as not to be output simultaneously from the OUTPUT 1 terminal and the OUTPUT terminal 2. Thereby, when the first and fourth output transistors 164 are turned on, the second and third output transistors 163 are not turned on, and a malfunction of the circuit, a circuit short circuit, and the like can be avoided.
　以上説明したように、電源スイッチ１１４がオフされている状態で、４つの出力トランジスタ１６１，１６２，１６３，１６４のうち１つの出力トランジスタ、ここでは第４出力トランジスタ１６４をオン状態にしておくことで、電源スイッチ１１４がオンされたとき、検出トランジスタ１３０のゲート端子をハイレベルからローレベルに切り替えることができる。つまり、４つの出力トランジスタ１６１，１６２，１６３，１６４のうち１つの出力トランジスタをオン状態にしておくことは、電池形電源装置１００による電源スイッチ１１４のオン／オフの検出を可能にする。電源スイッチ１１４のオン／オフを検出できるため、電池形電源装置１００がモータ１１５の正逆回転を可能にするためのＨブリッジ制御回路を備える場合であっても、既に説明したように、電源スイッチ１１４のオン／オフに連動して、電池形電源装置１００の通信機能のオン／オフ、通信間隔の変更等を行うことができる。 As described above, when the power switch 114 is turned off, one of the four output transistors 161, 162, 163, and 164, in this case, the fourth output transistor 164 is turned on. When the power switch 114 is turned on, the gate terminal of the detection transistor 130 can be switched from the high level to the low level. That is, if one of the four output transistors 161, 162, 163, and 164 is turned on, the battery-type power supply device 100 can detect the on / off of the power switch 114. Since ON / OFF of the power switch 114 can be detected, even when the battery-type power supply device 100 includes an H-bridge control circuit for enabling forward and reverse rotation of the motor 115, as described above, the power switch The communication function of the battery-type power supply device 100 can be turned on / off, the communication interval can be changed, etc.
　なお、第１乃至第５実施形態に係る電池形電源装置１００を構成する回路は、外部負荷と外部電源と電源スイッチとともに構成される回路である。したがって、外部負荷と外部電源と電源スイッチとを有する他の電子機器に、電池形電源装置１００の回路を組み込むことで、その電子機器は、第１乃至第５実施形態に係る電池形電源装置１００と同様の動作をし、同様の効果を得られる。 In addition, the circuit which comprises the battery-type power supply device 100 which concerns on 1st thru | or 5th embodiment is a circuit comprised with an external load, an external power supply, and a power switch. Therefore, by incorporating the circuit of the battery-type power supply device 100 into another electronic device having an external load, an external power supply, and a power switch, the electronic device can be configured as the battery-type power supply device 100 according to the first to fifth embodiments. The same operation can be obtained and the same effect can be obtained.
　ここでは、モータ１１５で発生したサージ電圧から出力トランジスタ１２０を保護するために保護用ダイオード１７１をモータ１１５に対して出力トランジスタ１２０と並列に、外側負極端子１０４から外側正極端子１０３に向かって順方向となるように配置し、外部電池３００によるリーク電流の発生を防止又は低減するために、ツェナーダイオード１７２を保護用ダイオード１７１と逆向きに接続した。しかしながら、外部電池３００によるリーク電流の発生を防止又は低減するための回路構成はこれに限定されない。 Here, in order to protect the output transistor 120 from the surge voltage generated in the motor 115, the protective diode 171 is forwardly directed from the outer negative terminal 104 toward the outer positive terminal 103 in parallel with the output transistor 120 with respect to the motor 115. In order to prevent or reduce the occurrence of leakage current due to the external battery 300, the Zener diode 172 is connected to the protective diode 171 in the opposite direction. However, the circuit configuration for preventing or reducing the occurrence of leakage current by the external battery 300 is not limited to this.
　図１５、図１６、図１７、図１８は、第２実施形態に係る電池形電源装置１００の他の例を示す等価回路図である。図１５、図１６、図１７、図１８を参照して、外部電池３００によるリーク電流の発生を防止又は低減するための他の回路構成を説明する。なお、第２実施形態を例に説明するが、リーク電流の発生を防止又は低減する他の構成は、他の実施形態に対して適用することができる。 FIGS. 15, 16, 17, and 18 are equivalent circuit diagrams showing other examples of the battery-type power supply device 100 according to the second embodiment. With reference to FIGS. 15, 16, 17, and 18, another circuit configuration for preventing or reducing the occurrence of leakage current by the external battery 300 will be described. In addition, although 2nd Embodiment is demonstrated to an example, the other structure which prevents or reduces generation | occurrence | production of leakage current is applicable with respect to other embodiment.
　図１５に示すように、モータ１１５で発生したサージ電圧から出力トランジスタ１２０を保護するとともに、外部電池３００によるリーク電流の発生を防止又は低減するために、保護用トランジスタ１７３が、モータ１１５に対して出力トランジスタ１２０と並列に配置される。ここでは、保護用トランジスタ１７３は、ＮチャンネルＭＯＳＦＥＴであり、そのドレイン端子は外側正極端子１０３に接続され、ゲート端子はＲＦＩＣ１２２のＯＵＴＰＵＴ２端子に接続され、ソース端子は外側負極端子１０４に接続される。また、ＯＵＴＰＵＴ２端子が開放されているとき、保護用トランジスタ１７３のゲート端子をローレベルで安定されるために、保護用トランジスタ１７３のゲート端子はプルダウン抵抗１７６を介してＧＮＤに接続される。保護用トランジスタ１７３は、ＲＦＩＣ１２２からの制御信号に従って、そのオン／オフが制御される。具体的には、保護用トランジスタ１７３は、ＲＦＩＣ１２２の制御に従って、出力トランジスタ１２０がオンからオフに切り替わる直前にオンされる。また、保護用トランジスタ１７３は、ＲＦＩＣ１２２の制御に従って、オンされてからモータ１１５で発生したサージ電圧が収まる一定時間経過後にオフされる。つまり、少なくともモータ１１５でサージ電圧を発生している間において、保護用トランジスタ１７３はオン状態である。したがって、出力トランジスタ１２０のオン／オフに伴って、モータ１１５でサージ電圧（逆起電圧）が発生しても、サージ電流は保護用トランジスタ１７３とモータ１１５とを含む閉回路で消費されるため、出力トランジスタ１２０のドレイン－ソース間にサージ電圧による高電圧がかからない。したがって、出力トランジスタ１２０をモータ１１５で発生したサージ電圧から保護することができる。 As shown in FIG. 15, in order to protect the output transistor 120 from the surge voltage generated in the motor 115 and to prevent or reduce the occurrence of leakage current by the external battery 300, the protection transistor 173 is connected to the motor 115. Arranged in parallel with the output transistor 120. Here, the protection transistor 173 is an N-channel MOSFET, its drain terminal is connected to the outer positive terminal 103, its gate terminal is connected to the OUTPUT 2 terminal of the RFIC 122, and its source terminal is connected to the outer negative terminal 104. Further, when the OUTPUT2 terminal is open, the gate terminal of the protection transistor 173 is connected to GND via the pull-down resistor 176 in order to stabilize the gate terminal of the protection transistor 173 at a low level. The protection transistor 173 is controlled to be turned on / off in accordance with a control signal from the RFIC 122. Specifically, the protection transistor 173 is turned on immediately before the output transistor 120 is switched from on to off under the control of the RFIC 122. Further, the protection transistor 173 is turned off after a lapse of a certain time when the surge voltage generated in the motor 115 is settled after being turned on in accordance with the control of the RFIC 122. That is, at least while the surge voltage is generated by the motor 115, the protection transistor 173 is in the on state. Therefore, even if a surge voltage (counterelectromotive voltage) is generated in the motor 115 as the output transistor 120 is turned on / off, the surge current is consumed in a closed circuit including the protection transistor 173 and the motor 115. A high voltage due to a surge voltage is not applied between the drain and source of the output transistor 120. Therefore, the output transistor 120 can be protected from the surge voltage generated by the motor 115.
　保護用トランジスタ１７３がオフ状態であるとき、保護用トランジスタ１７３により内蔵電池、出力トランジスタ１２０及び保護用トランジスタ１７３を含む閉回路は遮断され、内蔵電池のショートを回避することができる。また、保護用トランジスタ１７３がオフ状態であるとき、保護用トランジスタ１７３により外部電池４００、モータ１１５及び保護用トランジスタ１７３を含む閉回路を遮断でき、それにより外部電池３００のリーク電流を防止又は低減することができる。 When the protection transistor 173 is in the off state, the protection transistor 173 cuts off the closed circuit including the built-in battery, the output transistor 120, and the protection transistor 173, so that a short circuit of the built-in battery can be avoided. Further, when the protection transistor 173 is in the off state, the protection transistor 173 can cut off the closed circuit including the external battery 400, the motor 115, and the protection transistor 173, thereby preventing or reducing the leakage current of the external battery 300. be able to.
　保護用トランジスタ１７３は出力トランジスタ１２０がオフされる直前にオンされるため、保護用トランジスタ１７３と出力トランジスタ１２０とが共にオン状態である期間が発生する。何も対策を講じなければ、内側正極端子１０５から出力トランジスタ１２０、保護用トランジスタ１７３を経由して内側負極端子１０６につながる電流経路により、内蔵電池がショートしてしまう。ここでは、外側負極端子１０４から外側正極端子１０３に向かって順方向となるように、ショート回避用のダイオード１７７を保護用トランジスタ１７３と直列に接続することで、出力トランジスタ１２０と保護用トランジスタ１７３とが共にオン状態であるときの、内部電池のショートを回避することができる。 Since the protection transistor 173 is turned on immediately before the output transistor 120 is turned off, a period in which both the protection transistor 173 and the output transistor 120 are on occurs. If no measures are taken, the built-in battery will be short-circuited by a current path from the inner positive terminal 105 to the inner negative terminal 106 via the output transistor 120 and the protection transistor 173. Here, the output transistor 120, the protection transistor 173, and the protection transistor 173 are connected by connecting a short-circuit avoidance diode 177 in series so as to be in the forward direction from the outer negative terminal 104 to the outer positive terminal 103. When both are in the on state, a short circuit of the internal battery can be avoided.
　なお、出力トランジスタ１２０のオン／オフに保護用トランジスタ１７３のオフ／オンが同期できるのであれば、ショート回避用のダイオード１７７は省略することができる。また、ショート回避用のダイオード１７７を抵抗等で代替するで内蔵電池のショートを回避することはできる。 Note that if the protection transistor 173 can be synchronized with the output transistor 120 on / off, the short-circuit avoidance diode 177 can be omitted. Further, the short circuit of the built-in battery can be avoided by substituting the diode 177 for avoiding the short circuit with a resistor or the like.
　図１６に示すように、保護用ダイオード１７１をモータ１１５に対して出力トランジスタ１２０と並列に配置するだけでもよい。出力トランジスタ１２０の逆降伏電圧よりも低い順電圧特性を有する保護用ダイオード１７１を用いることで、モータ１１５で発生するサージ電圧から出力トランジスタ１２０を保護することができる。また、外部電池３００の合計電圧よりも高い順電圧特性を有する保護用ダイオード１７１を用いることで、外部電池３００によるリーク電流の発生を防止又は低減することができる。さらに、外部電池３００の合計電圧よりも高く、出力トランジスタ１２０の逆降伏電圧よりも低い順電圧特性を有する保護用ダイオード１７１を用いることで、モータ１１５で発生するサージ電圧から出力トランジスタ１２０を保護する機能と外部電池３００によるリーク電流の発生を防止又は低減する機能とを兼用させることができる。 As shown in FIG. 16, the protective diode 171 may be simply disposed in parallel with the output transistor 120 with respect to the motor 115. By using the protective diode 171 having a forward voltage characteristic lower than the reverse breakdown voltage of the output transistor 120, the output transistor 120 can be protected from a surge voltage generated in the motor 115. In addition, by using the protective diode 171 having forward voltage characteristics higher than the total voltage of the external battery 300, the generation of leakage current by the external battery 300 can be prevented or reduced. Furthermore, by using a protective diode 171 having a forward voltage characteristic higher than the total voltage of the external battery 300 and lower than the reverse breakdown voltage of the output transistor 120, the output transistor 120 is protected from a surge voltage generated in the motor 115. The function and the function of preventing or reducing the occurrence of leakage current by the external battery 300 can be combined.
　出力トランジスタ１２０がオンからオフに切り替わり、モータ１１５でサージ電圧が発生した場合、保護用ダイオード１７１はサージ電圧により導通する。それにより、サージ電流は保護用ダイオード１７１とモータ１１５とを含む閉回路で消費され、出力トランジスタ１２０に高電圧がかからない。そのため、出力トランジスタ１２０を、モータ１１５で発生したサージ電圧から保護することができる。一方、出力トランジスタ１２０が定常状態であるとき、保護用ダイオード１７１には低い逆方向電圧しかかからないため、保護用ダイオード１７１はオフ状態である。それにより、保護用ダイオード１７１とモータ１１５とを含む閉回路は遮断され、外部電池３００によるリーク電流の発生を防止又は低減することができる。また、保護用ダイオード１７１と出力トランジスタ１２０とを含む閉回路は遮断され、内蔵電池のショートを回避することができる。 When the output transistor 120 is switched from on to off and a surge voltage is generated in the motor 115, the protective diode 171 becomes conductive due to the surge voltage. As a result, the surge current is consumed in a closed circuit including the protective diode 171 and the motor 115, and no high voltage is applied to the output transistor 120. Therefore, the output transistor 120 can be protected from a surge voltage generated by the motor 115. On the other hand, when the output transistor 120 is in a steady state, the protective diode 171 is in an off state because only a low reverse voltage is applied to the protective diode 171. Thereby, the closed circuit including the protective diode 171 and the motor 115 is cut off, and the occurrence of leakage current by the external battery 300 can be prevented or reduced. Further, the closed circuit including the protective diode 171 and the output transistor 120 is cut off, and a short circuit of the built-in battery can be avoided.
　図１７に示すように、モータ１１５で発生したサージ電圧から出力トランジスタ１２０を保護するために保護用ダイオード１７１をモータ１１５に対して出力トランジスタ１２０と並列に、外側負極端子１０４から外側正極端子１０３に向かって順方向となるように配置し、外部電池３００により発生されるリーク電流を低減するために、低減用抵抗１７４を保護用ダイオード１７１と接続してもよい。この回路構成では、出力トランジスタ１２０のオン／オフに関わらず、保護用ダイオード１７１とモータ１１５とを含む閉回路は導通した状態である。モータ１１５にサージ電圧が発生したとき、サージ電流はこの閉回路で消費されるため、出力トランジスタ１２０を、モータ１１５で発生したサージ電圧から保護することができる。一方、出力トランジスタ１２０が定常状態であるとき、外部電池３００から閉回路にリーク電流が流れてしまう。しかしながら、この閉回路に抵抗値の高い抵抗１７４を介在させることで、そのリーク電流を小さくすることができ、それにより外部電池３００の消耗を低減することができる。 As shown in FIG. 17, in order to protect the output transistor 120 from the surge voltage generated in the motor 115, a protective diode 171 is connected to the motor 115 in parallel with the output transistor 120, and from the outer negative terminal 104 to the outer positive terminal 103. In order to reduce the leakage current generated by the external battery 300, the reduction resistor 174 may be connected to the protection diode 171. In this circuit configuration, regardless of whether the output transistor 120 is on or off, the closed circuit including the protection diode 171 and the motor 115 is in a conductive state. When a surge voltage is generated in the motor 115, the surge current is consumed in this closed circuit, so that the output transistor 120 can be protected from the surge voltage generated in the motor 115. On the other hand, when the output transistor 120 is in a steady state, a leakage current flows from the external battery 300 to the closed circuit. However, by interposing the resistor 174 having a high resistance value in the closed circuit, the leakage current can be reduced, and thereby the consumption of the external battery 300 can be reduced.
　図１８に示すように、モータ１１５で発生したサージ電圧から出力トランジスタ１２０を保護するために保護用ダイオード１７１をモータ１１５に対して出力トランジスタ１２０と並列に、外側負極端子１０４から外側正極端子１０３に向かって順方向となるように配置し、外部電池３００により発生されるリーク電流を防止又は低減するために、コンデンサ１７５を保護用ダイオード１７１と接続してもよい。コンデンサ１７５は電流の直流成分を遮断する。外部電池３００により発生されるリーク電流は直流であるため、保護用ダイオード１７１とモータ１１５とを含む閉回路に外部電池３００のリーク電流が流れない。したがって、コンデンサ１７５により、出力トランジスタ１２０が定常状態であるときの外部電池３００によるリーク電流の発生を防止又は低減することができる。モータ１１５でサージ電圧が発生したとき、瞬間的に発生するサージ電圧はコンデンサ１７５により吸収・低減され、それにより出力トランジスタ１２０をサージ電圧から保護することができる。 As shown in FIG. 18, in order to protect the output transistor 120 from the surge voltage generated in the motor 115, a protective diode 171 is connected to the motor 115 in parallel with the output transistor 120, and from the outer negative terminal 104 to the outer positive terminal 103. In order to prevent the leakage current generated by the external battery 300 from being reduced or reduced, the capacitor 175 may be connected to the protection diode 171. Capacitor 175 blocks the direct current component of the current. Since the leakage current generated by the external battery 300 is a direct current, the leakage current of the external battery 300 does not flow through a closed circuit including the protection diode 171 and the motor 115. Therefore, the capacitor 175 can prevent or reduce the occurrence of leakage current by the external battery 300 when the output transistor 120 is in a steady state. When a surge voltage is generated in the motor 115, the instantaneously generated surge voltage is absorbed and reduced by the capacitor 175, thereby protecting the output transistor 120 from the surge voltage.
