Abstract

The power breaking circuit is for cutting off the power connectdd to the ordinary circuit consuming a lot of power to extend the storing duration of the contents in a memory in case of discharging the battery to a certain low voltage. When a voltage level detector (1) detects the low voltage of the battery, switches (2,3) cut off the power connected to a load circuit (LOAD) and provide power only to a memory. When the receiver lies on the station, the battery is charged, and a reset circuit (5) turns on the switches (2,3) to provide power again.

본 발명은 무선전화기 휴대장치의 메모리 다이얼 기능이 부설된 제품을 사용함에 있어서 사용시에 밧테리 전압이 어느 지정된 전압까지 방전되었을 때 소비전류가 많은 일반회로의 전원을 차단시켜 메모리 보조기간을 더욱 연장시킬 수 있게함에 목적을 둔 무선전화기의 밧테리 전원전압 차단회로 장치에 관한 것이다.The present invention can further extend the memory auxiliary period by cutting off the power supply of a general circuit with a large current consumption when the battery voltage is discharged to a certain voltage when using the product equipped with the memory dial function of the portable telephone apparatus. The present invention relates to a battery power supply voltage blocking circuit device for a wireless telephone.

종래에 무선전화기 휴대장치의 메모리 다이얼 기능이 부설된 제품에서 밧테리 전압이 방전되어 기억된 자료가 소멸되는 결점이 있었다.Conventionally, in a product in which a memory dial function of a wireless telephone portable device is installed, a battery voltage is discharged and a stored data is lost.

본 발명은 종래의 결점을 적게하기 위하여 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in order to reduce the drawbacks of the prior art described in detail by the accompanying drawings as follows.

충전단자(A)에 다이오드(D1)과 다이오드(D2)를 병열연결하여 다이오드(D1)에 전원스위치(SW1)의 센터단자와 밧테리(DC) 및 다이얼 I·C를 연결한 저항(R1)을 접속하되 전원스위치(SW1)의 ON단자에는 써미스타(TH1)와 저항(R3)을 접속하여 직열연결시킨 가변저항(RV1)의 타단에 저항(R5) 저항(52)를 접속하여 전압레벨 감지기(1)를 구성하며 저항(R2)의 타단과 저항(R6)(R8) 및 트랜지스터(Q4)의 에미터 단자를 접속하되 다이오드(D2)는 저항(R4)를 직열연결하여 저항()와 트랜지스터(R5)의 베이스 단자에 저항(R7)을 연결시켜 구성한 리셋트회로(5)로서 트랜지스터(Q1)의 베이스에 접속하였으며, 트랜지스터(Q1)의 베이스단자에 저항(R5)이 연결되고 콜렉터 단자에 저항과 콘덴서를 접속하여 구성한 초기제어회로(4)를 트랜지스터의 베이스 단자에 연결하였으며, 트랜지스터의 콜렉터 단자에는 저항을 연결하여 구성한 스위치회로(2)로서 저항을 접속하여 트랜지스터(Q2)의 베이스 단자에 견결한 다음 트랜지스터(Q2)의 콜렉터 단자는 저항(R9)을 통하여 트랜지스터(Q3)의 베이스 단자에 연결하여 구성한 스위치회로(3)로서 결합된 것이다.Diode to the charging terminal (A) (D 1) and a diode (D 2) a byeongyeol connected to the diode (D 1) connecting the center terminal and the Battery (DC) and dial I · C of the power switch (SW 1) to the resistance Connect (R 1 ), but connect the thermistor (TH 1 ) and resistor (R 3 ) to the ON terminal of the power switch (SW 1 ) and connect the resistor (R5) to the other end of the variable resistor (RV 1 ). 52 to form a voltage level detector (1) and connect the other end of resistor (R 2 ) and the emitter terminals of resistor (R 6 ) (R 8 ) and transistor (Q 4 ), but diode (D 2 ) The reset circuit 5 was formed by connecting the resistor R 4 in series with the resistor R and the resistor R 7 connected to the base terminal of the transistor R 5. The resistor R 4 was connected to the base of the transistor Q 1 . resistor to the base terminal of the (Q 1) (R 5) is connected and connecting the initial control circuit 4 is configured by connecting a resistor and a capacitor to the collector terminal to the base terminal of the transistor And that, the collector terminal of the collector terminal of the transistor is connected to a resistance as the switching circuit 2 is configured by connecting a resistance gyeongyeol to the base terminal of the transistor (Q 2), and then the transistor (Q 2) is through a resistor (R 9) It is coupled as a switch circuit 3 constructed by connecting to the base terminal of the transistor Q 3 .

이와같은 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as follows.

제 1 도는 전원스위치(SW1)을 온(ON)위치로 놓으면 밧테리 전원이 초기제어회로(4)를 동작시켜 스위치(2)FF 구동하여 스위치(3)을 동작시켜 전원을 부하회로에 공급한다. 전원레벨감지기(1)은 밧테리 전압이 지정된 전압까지 방지되면 감지하여 스위치(2)를 동작시켜서 스위치(3)의 동작을 정지시켜 부하(LOAD)회로에 공급하던 전원을 차단시키고 메모리다이얼리에만 전원을 공급하므로 메모리 보존기일은 상당히 길어진다. 차단된 전원을 복원시키기 위해서는 휴대장치를 고정장치에 올려놓아 충전상태가 되면 리셋트회로(5)에 의하여 스위치(2)를 구동스위치(2)을 동작(ON)시켜 다시 전원이 공급된다.1 shows that when the power switch SW 1 is set to the ON position, the battery power source operates the initial control circuit 4 to drive the switch 2FF to operate the switch 3 to supply power to the load circuit. . The power level sensor 1 detects when the battery voltage is prevented up to a specified voltage, activates the switch 2 to stop the operation of the switch 3 to cut off the power supplied to the load circuit, and to supply only to the memory dial. The memory retention period is considerably longer. In order to restore the interrupted power, when the portable device is placed on the fixed device and is in a charged state, the power is supplied again by operating the switch 2 by the reset circuit 5 and turning on the driving switch 2.

제 2 도는 상세도로서 전원스위치(SW1)을 온(ON)위치에 놓으면 저항(R2)와(R5)를 통하여 트랜지스터(Q1)의 베이스에 전압이 가해져 (Q1)의 동작하며 (Q1)의 콜렉터는 로우레벨이 되어 트랜지스터 (Q2)의 베이스에 저항 (R5)를 통하여 가해진 전압을 로우레벨로 만들어 (Q2)의 동작을 정지시킨다. 저항 (R6)을 통해 트랜지스터 (Q3)의 베이스에 전압이 가해져 (Q3)의 콜렉터가 로우레벨이 되어 트랜지스터 (Q4)를 온(ON)동작시키므로 (Q4)의 에미터에 걸린 전원전압이 (Q4)의 콜렉터를 통해 부하에 전원을 공급한다. 가변저항 (RV1)에 의해 트랜지스터 (Q2)의 베이스에 걸리는 전압이 지정되여 밧테리 전압이 지정된 전압이하로 떨어지면 트랜지스터 (Q1)이 오프(OFF)되여 (Q1)의 콜렉터가 하이 (H1)레벨이 되어 트랜지스터(Q2)의 베이스가 하이레벨이 되므로 트렌지스터

Figure kpo00001
가 온(ON)되면 트랜지스터(Q3)의 베이스가 로우(LOW)레벨이 되어 트렌지스터
Figure kpo00002
이 오프(OFF)된다. 그러면 트랜지스터(Q4)가 오프(OFF)되어 부하회로에 공급되던 전원이 차단된다. 이때 차단된 전원을 부하회로에 다시 공급하기 위해서는 충전단자에 하이레벨의 전압을 걸어주면 리셋트(RESET)된다.FIG. 2 is a detailed view. When the power switch SW 1 is set to the ON position, voltage is applied to the base of the transistor Q 1 through the resistors R 2 and R 5 to operate the Q 1 . The collector of (Q 1 ) becomes low level and stops the operation of (Q 2 ) by making the voltage applied through the resistor (R 5 ) to the base of the transistor (Q 2 ) low. A voltage is applied to the base of transistor Q 3 via resistor R 6 , causing the collector of Q 3 to go low level, thereby turning on transistor Q 4 , thereby trapping the emitter of Q 4 . The supply voltage supplies the load through the collector of (Q 4 ). When the voltage applied to the base of the transistor Q 2 is specified by the variable resistor RV 1 and the battery voltage falls below the specified voltage, the transistor Q 1 is turned off and the collector of Q 1 becomes high (H). 1 ) the transistor becomes high and the base of transistor Q 2 becomes high level
Figure kpo00001
When turned on, the base of transistor Q 3 goes low and the transistor
Figure kpo00002
Is turned off. Then, the transistor Q 4 is turned off and the power supplied to the load circuit is cut off. At this time, in order to supply the interrupted power to the load circuit again, a high level voltage is applied to the charging terminal.

이와같이된 본 발명은 밧테리 전압이 어느 지정된 전압까지 방전되었을 때 소비전류가 많은 일반회로의 전원을 자동적으로 차단시켜 주게 되므로 메모리의 보존기간을 더욱 연장시켜줄 수 있는 효과를 얻을 수 있는 것이다.The present invention as described above is to automatically cut off the power supply of a general circuit with a large current consumption when the battery voltage is discharged to a certain voltage, it is possible to obtain an effect that can further extend the retention period of the memory.
