1332302 U0: power management control circuit 4〇9: selector circuit 411: control circuit '8. If there is a chemical formula in this case, please disclose the chemical formula which can best display the characteristics of (4). Description of the invention: [Technical Field of the Invention] The present invention It is a topology structure (t_qing) about power management, and is a battery charge controller (controliers). ^ ° [Prior Art] A variety of portable electronic devices have a power supply system that monitors, controls, and indicates the various system power supplies to the electronic device. These power supplies typically include a fixed output AC to DC adapter and one or more rechargeable batteries. The power system includes a power conversion block, such as a DC to DC converter that converts a fixed DC voltage provided by the ACDC adapter into a precisely controlled variable DC voltage output to Charge the battery. 5 The power system supplies power to the system from the ACDC adapter or the main battery, and if the appropriate conditions are met, the battery is charged. As such, there is typically an ACDC power switch for selecting the ACDC adapter to the system, and a battery switch for selectively coupling the main battery to the system, and a main battery connectable to the main battery A charging switch to an output of the DC to DC converter for charging. When the ACDC adapter is powered to the system, the ACDC's power-on relationship is closed (ci〇sed), the battery is disconnected = (〇pen), and the charge switch can be closed or open. In contrast, when the battery is powered to the system, the battery open relationship is closed and the ACDC power switch and the charge switch are both open. In order for the battery to be charged to its maximum operating voltage, the output voltage of the ACDC adaptation is typically selected to be higher than the maximum operating electrical waste of the battery (typically at least 1 to 2 volts higher). Because the output voltage of the ACDC adapter is a fixed value, the output voltage of the battery can be changed greatly (according to the state in which it is charged), so the ACDC adapter and the battery cannot be coupled in parallel for a certain period of time to supply power to The system is loaded. This voltage difference can result in unwanted internal current generation from the higher voltage source (ACDC adapter) to the lower voltage source (battery). As a result, to address the need for transient high voltages in the system, the ACDC adapter is typically oversized, thereby significantly increasing the cost of the power system. In addition, because the output voltage of the ACDC adapter is fixed, its output voltage cannot be used to charge the battery that defines the precise charging voltage and current control. Thus, there must be a DC to DC converter to complete the second power conversion step. This second power conversion step further increases the overall efficiency of the power system. Thus, there is a need in the art for a power management topology that a power management topology can provide a controllable/DC output to the system load and the battery can be coupled in parallel with only one power conversion. A controllable DC power source and battery power supply to the system load, or both. SUMMARY OF THE INVENTION An advantage of the present invention is to provide an efficient, circuit-clearing G: to reduce charging time and cost. The invention is a method for charging a battery. The square=the voltage generated by the voltage of the pool is compared with the value of the slave voltage representing the maximum battery ^, and the generated one represents one

J stream, two signals to the battery. The voltage value of the second signal is selected from the first signal and the settable voltage value. The invention provides a variable wake up level circuit (variable wake up level)

The road is touchable - a sister's money'. The recording wire - a charging electric power supply to the battery X. The variable inclination circuit includes a signal processing circuit and a comparison circuit. The signal processing circuit can be an summmg-type circuit that receives a first settable voltage that represents a minimum wake-up current and receives a third signal that represents - Battery voltage. The signal processing circuit is adapted to produce a first output signal ' whose voltage value is dependent on the first settable voltage and the second h value. The comparison circuit is adapted to receive the first round number and the second settable, the second settable voltage represents a maximum wake-up current, and the comparing circuit generates the wake-up signal. The wake-up signal selects a smaller value voltage value from the voltage values of the first output signal and the second settable voltage. The present invention also provides a variable wake up current circuit 'the current circuit can be set at least through a current flow control device (current fi〇w CC) ntlOmng device connected in series to the battery charging path) And control a wake-up current that supplies a battery. The variable wake-up current circuit includes a variable wake-up value circuit, an error amplifier, and a driving circuit. The can 7 1332302

The wake-up value circuit reacts a first-signal representing the instantaneous voltage of the battery, reacting with a first settable voltage representing a minimum wake-up power of the battery; and reacting a second settable voltage 'This voltage represents a large allowable wake-up current for the battery. ^ The variable wake-up value circuit can also generate a wake-up 彳S number' which represents the wake-up current for charging the battery. The voltage value of the wake-up signal depends at least on the first settable voltage and the voltage values of the first signal. Weaving amplifying ^ receiving the touch difficulty number and - a battery current detection signal 'The battery current detection signal flows through the battery--charged flow of the battery. The multiplexer reacts the difference between the wake-up signal and the battery current detection signal to generate an error signal. The drive circuit is adapted to at least react to the error signal to output a device drive signal. The device driving signal maintains the instantaneous charging current at a certain value according to the device (4). The invention also provides a battery charging device. The battery charging device includes an electric path to a rechargeable battery, (4) a power in the current path: a control unit and a variable tilt current circuit. The current control is adapted to control the charging current supplied to the battery. The variable wake-up current ^

Table 180 shows switches SW1 and S in various power modes. In one embodiment, the controllable DC power supply 1〇4 can be a further detail controllable adapter, such as an ACDC adapter. The adapter only needs to convert the power supply to supply the crane load 11Q and ^ This 'powerful power system usually needs - an extra power switch == a solid-turn converter provides a precisely controlled output... battery Charging) is not required in this embodiment. The electronics are known in the art as computers, mobile phones, personal digital assistants, power tools, electrics. The controllable DC power supply 104 provides a dynamically controllable DC. The power supply 1〇4 is a controllable adapter or DC. The controllable flow source 104 can be separated or integrated into the 3, set to 100. The battery 105 includes one or a plurality of f-cells. i 疋 '^ Different types of rechargeable batteries' For example, a rotor battery, an x-recording battery, a hydrogen recording battery, or the like. ‘, Selective 114 The king’s illusion is connected to a point 116. The battery 105 can be selectively coupled to the node 116 via a path 118. The system is routed to the node 116 via the path fm. The μm m can also be used to indicate that the two power management control circuits 13 are different from the present invention in controlling and indicating that the power supplies 104, 105 are powered to the system load 110 = charging the battery. The power management control circuit 130 can be used to input money. These input money can be used to charge various power states, for example, an output voltage value of the battery 105 is the same as that of the power supply of the DC power source, for example, the output power of the power supply 1G4. Chi motor value. The negative residual state of the system load 110 can be a power-like output of 9 watts of the system load required - an electrical surface or a required management control circuit breaker: the power supply such as i often 'the electric county paste circuit 13() can be controlled by the value of the output voltage value along the path 133, and can be controlled by the signal along the path 20 to control the state of the switches SW1 and sw2. In the advantage of a plurality of power supply embodiments, the power management controls the power mode 185 detailed in $10 such that the power can be supplied to the system load 110. Parallel light ^=The DC power supply 104 and the battery 1()5 have a problem that the difference between the two is different (4), resulting in a higher voltage-critical power supply - an unwanted current (inter-current). The desired internal current can be prevented from flowing in the other direction by the unidirectional switch and the selective one-way switching. For example, 2 'under buffer battery power mode 185', as shown in Table 18, allows current to be switched as a selective unidirectional switch, and open can be a unidirectional switch. In addition, when the battery voltage changes, for example, according to the data state, the switch SW2 may include a bidirectional discharge switch, which can be maintained within an allowable range of the voltage value of the controllable DC power source 1〇4. Controls the unwanted internal current between the DC power source 1G4 and the voltage = voltage. The parallel power mode 185 can be selected by the command h number received via path 141. This power mode 185 can also be selected in response to a power crisis condition. This power crisis condition occurs when a load demand of the system load 11() exceeds the maximum allowable 1332302 power of the controllable DC power source 1〇4 alone and exceeds the maximum allowable power of the battery 105 alone. However, the power supply can provide sufficient power to meet the load requirements of the system load 110 for the necessary period of time. Therefore, the controllable DC power source 1〇4 can be oversized to cope with this situation.

In a parallel power supply mode 185, another advantage of the power management control circuit 130 is to prevent crossover between the controllable DC power source 104 and the battery 1〇5 by controlling the state of the switches SW1 and 2 Conduction. Switch SW2 can be a selective unidirectional switch, and switch SW1 can be a one-way switch. That is, the switch SW2 can allow current to flow only in one direction depending on whether the selected power supply mode is closed or turned off. When the system load 11 is only powered by the controllable DC power source 104 (and thus the switch SW1 is closed) and no charging occurs (power mode 181), the switch SW2 can be turned off.

Switch SW2 can have a first-to-release state where current is typically only allowed to flow from the battery. For example, in this first discharge closed state, current is allowed to flow from the battery 105 to the system load 110, but current is not allowed to flow from the controllable DC power source 104 to the battery 1〇5. In addition, switch SW2 can also have a second charge closed state, where only current is allowed to flow to the battery. For example, in this second charge closed state, only current is allowed to flow from the controllable DC power source 1〇4 to the battery 105, preventing flow from the battery 105 to the system load 11〇. The switch can be a one-way switch. When the switch SW1 is closed, only current is allowed to flow from the control DC power source 104 to the node 丨16. Therefore, at the time when the controllable DC power source 1〇4 and the battery 1〇5 are simultaneously supplied to the parallel load supply mode of the system load 110, the switch SW2 can be closed and the switch SW1 can be closed. Therefore, the battery 1G5 = supply current to the system load 11Q, and the unwanted internal current from the controllable DC power supply (10) to the pool 105 can be prevented by the switch SW2. In addition, the two-component DC (4) 4 branch _ current can be used by those skilled in the art to understand various methods that can be implemented to select a unidirectional switch. For example, a pair of switches coupled in series with each other, and a pair of diodes associated with each pair in parallel may be employed. A special diode can stop current flow to a certain direction, while a side switch can allow current to flow in both directions. One advantage of the power management control circuit 130 is that another or 183 can be selected, where the controllable DC power source 104 can be powered to the system. In this example, the battery 1G5 can be charged (the supply of the table (10)) or not charged. (Power mode (8) of Table 180). A signal 'in the complex number of the power management circuit 130; a signal ' can represent a power of the system load 110, a voltage demand, a current demand, and the like. Advantageously, the SinTI/circuitry 130 can react to the signal to adjust the controllable DC output parameters, such as the input (four) voltage value, the input (four) current value, etc., 130, and the demand for the load 110. In a certain amount, the power management circuit i 1 controls the voltage value of the DC power source 104 so that the basin is within the required voltage range. Therefore: the ?= towel's description of the dragon buffer battery can be used to supply the system according to the needs of the power supply system (such as Table 180) or does not exist (, in addition to the controllable adapter l〇4a, Figure 2 The thousands of wishes + / its components are similar to the figure i and the same label. = the repeated description of these components. This: for the second five see here to omit the controllable AC to DC adapter, the adapter receives the conventional Intersection 1332302 = from the power management control circuit 13_ a control along path 133 converts it to a controllable DC voltage value. Controlled by the power supply, the circuit 130 controls the plurality of parameters of the controllable adapter, including Ϊί,, maximum output power, maximum output current, Qiqishan ^ start β 疋 (Pr〇flle), etc. The output voltage of the controllable adapter 104a can be dynamically adjusted by the power management control circuit 13〇 As shown in FIG. 3, the controllable DC power supply in FIG. 1 may be a DC-to-DC conversion that is subtracted from the path 14.

- A switch swi and a fixed adapter 3G2. As shown, the switch is torn across the path between the DC to DC converter face and the node 116. In addition, the switch SW1 can also be coupled to the path 114 between the fixed adapter 3〇2 and the §A”IL turn-to-turn, L-converter 〇4b, which is implemented in the other real hoods of FIGS. 9-15. Step Wei.

- The embodiment shown in Figure 3 is a two-stage power conversion instead of the = power conversion shown in Figure 2. That is, the fixed adapter view and the DC to DC conversion = ^ 4b of the power conversion. The embodiment shown in Fig. 3 still causes the power supply system to operate in a buffered battery power mode 185, for example, such that the battery and the controllable DC power supply 104b are simultaneously powered to the system load no as previously described. Except for the DC, DC converter 104b and the fixed adapter 302, the other components of the electrical system shown in Fig. 3 are similar to those shown in Fig. 1 and have the same reference numerals. Therefore, repeated description of these components is omitted herein for the sake of clarity. The DC to DC converter 104b can be any of a variety of converters controlled by various control signals from the power control circuit 13 along path 303. In one embodiment, the DC-to-DC converter 1〇4b may be a buck converter with a high side switch and a low side switch LC instrument in the field ( Buck Converter). From this, the control signal of source control circuit 130 can be a pulse width modulation (PWM) signal. The pulse width control of the Pp signal is "closed, the period of the state (the high-side switch is closed and the low-side switch is open) and the "off" state (the high-side switch is open and the low 13 1332302 is closed) to control the DC transfer. The output of the DC converter 1〇4b is electrically connected to the current value. As shown in Figures 4 to 8, the power supply system of the different embodiments of the present invention = the controllable adapter 1〇4a and the two of the controllable DC power source 104 Battery cell A and battery B). Thus, in the embodiment shown in Figures 4 to 8, the controllable adapter 10a4a supplies power to the system load 11〇 and the battery 1〇5, ^ only-level Power conversion. The embodiment of the power conversion can be used separately for the aforementioned buffer battery mode to simultaneously supply the battery and the current source to the system load 11 〇. The other embodiments of FIG. 9 to FIG. 15 are replaced; tn: the controllable DC-to-DC conversion of the DC power supply 1〇4, state 104b, and also two batteries (Battery A and Battery B). The adapter 302 and the DC to DC converter are input, and the embodiment of Figures 9 to 15 is at least The power conversion is performed twice. The embodiment shown in FIG. 4 can be implemented with FIG. 2 and FIG. 2; however, the embodiment shown in FIG. 4 may or may not have the aforementioned DC power supply in parallel to the system load. This mode of 11 。. For example, a particular power supply system may only want the primary power conversion without the buffered battery power supply mode. Figure 4 = Some components are similar to those of Figure 2, and the labels are the same. The repeated description of the repeated components and functions is omitted here. The "controllable parent-to-work DC adapter 1〇4a, the battery pack, or the battery β or a combination thereof' can be powered by the power management control room. _Caring the _ Η 1Η) Receive power via the road ^^ =116. The controllable adapter can be selectively thinned by I SW1 and path 114 to node 116. Battery A, 1 switch SW2A* path 118a is consuming at node 116. The same pool can be an independent external switch via switches SW2B and _118b_ to node 116. The switch SW1 can also be a one-way switch as described in T 1 1332302. The M SW2A and the switch sra may be independently closed or embedded in the battery packs IGa and 11a respectively, for example, for extending the battery life = using the electric energy in the battery pack to reduce the power switch And related power loss. The switch SW2A and the switch SW2B may also be the aforementioned selective unidirectional switches.

As described above, the power management control circuit 13 can receive different input signals via different paths. In the embodiment shown in FIG. 4, an adapter detecting resistor 4, a system detecting resistor 3, a battery A detecting resistor 7 and an electric f detecting impurity 5, the wire is shown along the respective electric_path to the power management control ^ The input signal of the current value of circuit 13G. For example, the adapter sense resistor 4 provides a data indicating the current flowing along the path 114 from the controllable adapter. The system sense resistor 3 provides a data signal indicative of the current flowing from any source 路径 to the system load 11G along path 121. The battery A withering 7 provides a data signal indicative of flow or flow to the battery A along the path, such as current. Finally, the battery (10) sense resistor 5 provides a data signal indicative of the current flowing or flowing from the battery along path 118b. The upper Γ indicates the input signal of the voltage value (VFB-A) of the electric power, the voltage ϊ of the battery B, and the voltage value of the secret load (VFB-SYS).

The power management control circuit 13G. In addition, an input signal, such as a bedding signal, can also be input from a main power management unit (pMU) 12 to the power management control circuit 13 via the main bus bar 22 (^pM[J12 can operate in the field] Various power management programs are known. These input signals from the ^ include, but are not limited to: charging current, charging voltage, preset voltage, adapter power limit, adapter current limit, = = = sub, battery presence, plural Warning signals such as overvoltage, overshoot, charging, over power of the adapter 104a or the system 11{). The master/sink row 22 can have a plurality of lines and can carry analog and digital command signals. For example, if the ΡΜϋ 12 is programmed to operate an SMBus protocol, the main bus can be an SMJBus. . The PMU 12 can be a 15 ί component, or it can be embedded in the electronic device - a more complex process of stealing. In addition, a battery bus 24 of the battery pack and the battery pack can provide a message to the lion management control circuit 13(). Through this bus 24, such a message can be provided, which can represent various parameters including, but not limited to, charging power, charging voltage, battery presence, and multiple signals such as overvoltage, overheating or overcurrent. For the power management control circuit 13Q, it may include: a main interface current detecting amplifiers 14, 15, 17, 18, and associated control and detection circuits 16 and the determining circuit 16 further includes a The selector circuit 409, the one provided via the bus bar 20, is a "Λ真I interface' plan to receive the slave circuit 12; The voltage and current limits are communicated to the determination signal to the battery pack, the battery pack, the controllable adapter, and the Lie load 110. The main interface 13 can receive analog and digital signals from the =12. If the Jane 12 provides a digital signal, the main interface can be referred to as 'an SMBus or I2C interface'. In this example, a multi-multiplexer (臓) and a digital-to-analog conversion 13 are used to convert the digital signal into an analog signal ' and provide a suitable number ^ ^ the decision circuit 16. The MUX can be any number | ^ than k5 tiger,. It depends on the number of signals supplied to the decision circuit I6. Because, the detection resistance is usually very small, so the party 丨 4, 15, 17, and Mo Da from each: check: 3 = stream 5 check = 1332302 signal. For example, sense amplifier 4 amplifies the system to detect the voltage drop across the resistor 3 and provides a 丨SYS^ number indicating the current along path 12i. The cardiometer amplifier 15 amplifies the electrical 'voltage drop' across the adapter sense resistor 4 and k for an iad signal indicative of the current through the path 114. Sense amplifier 17 amplifies the voltage drop 7 ^ on the battery B sense resistor 5 to provide an iCDB signal indicative of the current along path 118b. Finally, the sense amplifier 18 amplifies the voltage drop across the battery A sense resistor 7 and provides an icda signal indicative of the current along path 118a. , . The ISYS, IAD, ICDB, and 1CDA signals from the sense amplifiers 14, 15, 17, 18 are then provided to the decision circuit 16, and in particular, to the control circuit 411 of the decision circuit 16, respectively. Further, the VFB_SYS signal indicating the voltage value of the load 110, the VFB_B signal indicating the voltage value of the battery B, and the VFB_A signal indicating the voltage value of the battery person may be supplied to the determination circuit. 16. Specifically, it is a portion of the control circuit that is provided to the decision circuit 16. The control circuit 411 receives input signals such as ISYS, IAD, ICDB, ICM, VFB-B, and VFB_A, and compares these signals with, for example, respective thresholds (thresh〇ld) provided by the pMU 12. Based on these comparisons, the first set of output signals provided by the control circuit 411 controls an output parameter of the adapter 104a, such as an output voltage value, via the appropriate g" The output of the 苐 group controls one or a plurality of output parameters of the controllable adapter 〇4a, so that the power supply accomplishes various tasks, including various operations as in the foregoing FIGS. 1 and 2. In addition, this work may also include, but is not limited to, at least one of the following tasks: 1. Providing all of the required adapter currents to a maximum, current output value of the adapter, up to the power supply limit of the system load 11Q; If necessary, a charging current can also be supplied to charge the battery 1〇5; 2. during a charging mode, the total current output value of the total charging 17 1332302 that is transmitted to the battery 1〇5 is limited to the maximum output current value of the adapter 104a. The system load 110 is between the difference in the required current value; ' 3. As long as any one of the batteries does not reach the maximum charging voltage, the maximum charging current is supplied to each of the batteries (Battery A and Battery B); Providing the maximum charging current to the lowest voltage battery if any of the batteries does not reach the maximum charging voltage; and 5. providing a set of maximum supply voltage to the system load when there is no battery or no charging request is received 11〇.

Still other embodiments of the embodiment of Figures 1 and 3 include a DC to DC converter 104a as the controllable DC power source 104, a fixed adapter 302 and two batteries as the battery source 105 ( Battery A and Battery B). In summary, the embodiment shown in Figures 9-15 and Figures 1 and 3 as previously described The main difference is that the number and the position detecting resistor along various power paths used.

The embodiment shown in Fig. 9 includes a detecting resistor 4 of a DC-DC converter, a system detecting resistor 3, a detecting resistor 7 of a battery A, and a detecting resistor 5 of a battery β. The embodiment shown in Fig. 10 includes a sense resistor 4 for DC-to-DC conversion, a sense resistor 7 for a battery a, and a sense resistor 5 for a battery B.

An output path of the DC-to-DC converter is connected in series to the detection resistor 3 of the DC-DC converter and a battery detection resistor 5. Most, the embodiment shown in FIG. 15 includes a suitable detecting resistor 4 coupled to an input end of the fixed adapter 3〇2 and an input end of the DC-to-DC converter 1〇4b, and A battery eight detects the resistor 7 and a battery sense resistor 5. In some examples, one or more of the batteries may be deeply discharged. That is, the discharge of the battery _ the battery's output dust may be lower than the battery and / I, the minimum voltage necessary for normal operation. When it comes to such a deep pool. 'Fish/Filling', it is necessary to provide a wake-up battery charging current to the electric /, the positive ten charging current compared to the usual wake-up battery charging current value relative to 20 f: the usual charging current of the dish. Similarly, the value of the charging voltage of the wake-up battery is relatively small compared to (4). When the lightning voltage exceeds the threshold of a wake-up threshold, the normal charging charge is applied, and if a normal charging current is used, the deep discharge battery will cause the battery to age. . In some battery-powered topologies, 'the battery and the system load can be powered by a power supply' so that a power supply, such as a DC to DC, provides a reduced charge current for a deep discharge battery and The battery is powered by a different power source, such as an ACDC adapter, to provide a relatively high current and voltage to the system load. The battery-powered topology of the embodiment shown in FIG. 1 is a power source (eg, controllable DC power source 104) that supplies both the system load 11G and the battery 1G5 (as in the power mode 183 in Table 180). Therefore, 'if there is an alternative method that can provide a wake-up charging current for the battery 105 and provide the required voltage for the system load 11 ,, the advantages will be obvious. Figure 16 shows another embodiment of an electronic device 1600 that includes a controllable DC power source 104 and a battery A that can be individually or collectively powered to the system load 110. In Fig. 16, there are some of the same reference numerals as in the drawings, and the description of these overlapping components is omitted here for the sake of clarity. As shown in Fig. 16, only one battery, battery a, and selective unidirectional switch SW2A associated therewith are shown. Of course, additional batteries and additional associated selective unidirectional switches in parallel with battery a can also be used. In the embodiment shown in Fig. 16, the selective one-way switch SW2A corresponding to the battery A can be realized by using the switches SW2A1 and SW2A2, wherein the switches 2A1 and SW2A2 each have a diode D1 and D2 connected in parallel therewith. When the parent switches SW2A1 and SW2A2 are closed, the current can be allowed to flow in both directions in both directions. However, when one of the switch SW2A1 and the SW2A2 is turned off and the other is closed, the switch SW2A can realize the function of a selective unidirectional switch, that is, the body diode D1 connected in parallel with the open switch. Or D2, allowing the electrical 21 1332302 flow to flow in one direction while blocking the reverse current through a disconnected switch. For example, as described in detail in Table 1680, switch SW2A1 may be closed and switch SW2A2 may be open in a charge supply mode 183, . Therefore, the charging current from the power source 1 〇 4 can charge the battery A through the closed switch SW2A1 and the diode D2 in parallel with the open switch SW2A2. However, in this charging power supply mode 183, the current in the opposite direction from the battery pack to the system load 11 is prevented by the diode D2. Advantageously, the power management control circuit 1630 can include a wake-up circuit 1608. The wake-up circuit 1608 will respond to the different input and/or command signals, providing a control signal to the selective unidirectional switch SW2A via path 20. The control signal provided by wake-up circuit 1608 can represent a wake-up state or a normal state of charge. The selective one-way switch SW2A allows only one wake-up charging current to flow to the battery a when reacting to a wake-up state signal. The selective unidirectional switch SW2A can allow normal charging current to flow to the battery A when reacting to a normal state of charge signal. As shown in Fig. 17, the power management control circuit 1630 and the wake-up circuit 16A in Fig. 16 are described in detail. For the sake of clarity, only switch SW2A in the selective unidirectional switch SW2A of Fig. 16 is described in Fig. 17. The wakeup circuit 1608 may include a comparison circuit 1718 and an output decision circuit 1612. The comparison circuit 1718 can include an error amplifier πιο. When the system is in the state of the charge mode 183 as described in Table 1680; X the error amplifier 1610 can receive an ICDA signal at its inverting input indicative of a momentary charge current supplied to the battery A. The iCDA signal is provided by the sense amplifier 17 via path 1706. The non-inverting input of sense amplifier 17 can be coupled to contact 1702' with its inverting input coupled to contact 1704. A wire may be connected across the battery A sense resistor 7 and connected to the contacts 1702, 1704' to provide an input signal to the sense amplifier 17, the charge indicating the charge provided to the battery A in a charge mode. Current. 22 The error amplifier 1610 can also receive a signal at its non-inverting input that represents a wake-up current value of a preset value. The preset wake-up current value can be a fixed or programmable current value to accommodate different battery sizes, types, and charging conditions. This signal representing the wake-up current can be sourced from a variety of sources, including a signal from a PMU 12 via the primary interface 13. The error amplifier 1610 then compares the signal indicative of the instantaneously charged current value to the ICDA signal indicative of the wake-up current value and provides a comparison output signal to the output decision circuit 1612. The output decision circuit 1612 in the wake-up circuit 1608 receives various input and/or command signals including the comparison output signal from the comparison circuit 1718 and a selector_number from a selector circuit 409 via path 1714. The output decision circuit 1612 can provide the comparison output signal or the selector signal to a control terminal of the switch SW2A1 to control an on state of the switch SW2A1. The output decision circuit 1612 can include a variety of functions required by logic circuits well known in the art. When the output decision circuit 1612 supplies the comparison output signal from the comparison circuit 1718 to the switch SW2A1, the switch SW2A1 reflects the signal to limit the charging current value supplied to the battery A to the wake-up current value. In one embodiment, the switch SW2A1 can provide battery A with a constant current equal to the wake-up charge current value. The comparison output signal can be an analog signal, and the switch SW2A1 can react to such a ratio signal and enter an intermediate conduction state. An "intermediate conduction state" as used herein refers to a state in which at least a slight limit current flows from one end of the switch to the other end. Thus, in the case where the battery A is deeply discharged, the switch SW2A1 in the intermediate conduction state can limit the current supplied to the battery A to a wake-up current value. In one example, when the switch SW2A1 receives the comparison output signal from the comparison circuit 1718, the switch behaves like a resistor controlled by an error amplifier. The switch SW2A1 can be any type of transistor and can accept any type of analog signal. For example, the switch can be a field effect transistor whose gate 23 signal is recorded. The collector of the current analogy and the electric one of the shot ===

When the switch 1612 provides the selector output signal, the open _" Ζ ^ sign is finely closed or disconnected. The number is given by the selector circuit, so that if the digit is a digit 1 = L = two, the switch should be closed when the selector outputs a signal, and 1 f can be in a fully-on state. The term "疋王" is a kind of current flowing from one end of the switch to the other end.

The state of any restrictions. Therefore, if the switch sw2ai is closed by reacting the selector output signal, the normal charging current value can be supplied to the battery A. Therefore, the comparison output signal ', for example, an analog signal in the embodiment of the present invention, can be used to control the switch 8 when the battery A is deeply discharged, and the charge current can be limited to a wake-up charge current value. Moreover, the selector output signal, such as a digital signal in the embodiment of the present invention, can be used to control switch SW2A1' and provide a higher normal charge current value to battery a. The output decision circuit 1612 can also receive additional input and/or command signals via the bus bar 16丨4. Such signals may be provided by a number of sources, including through the PMU 12 of the primary interface 13, which may be provided by the power management control circuitry 1630 or may be externally set by the power management control circuitry 1630. This type of signal received via bus 1614 can be an enabling signal. If the enable signal is in a first state, such as a digit 1 ', the output decision circuit 1612 can be enabled to provide the comparison output signal from the comparison circuit 1718 to the switch SW2A1. If the enablement message 24 can be another open circuit, the circuit is 1612. If the battery s shows ===;, the voltage value exceeds the threshold of the battery

The battery receives the tilting charge current for more than ^ = ===, and the electrified triHjr provides a wake-up circuit. The circuit includes a ratio of ~ than the circuit to receive a signal indicating that two batteries are provided via one path. The first value of the charging current value and the recording of a ^

'Awakening the second signal' and providing a comparison output signal that the comparison circuit reflects the first and second signals. The wake-up circuit can also include an output=determination circuit adapted to receive at least the comparison output signal and a selector signal from a selector circuit, the output decision circuit comparing the output signal to the selection One of the signals is provided to a switch to control a state of the switch coupled to the path. In another embodiment, a device is provided that includes a wake-up circuit consistent with the previously detailed embodiments. In another embodiment, a device is provided, the device comprising: a first path designed to be coupled to a controllable DC power source; a second path designed to be coupled to a battery; And a third path coupled to a system load, wherein the first, second, and third paths are coupled to a total of 25 1332302, and the first node and the first path are connected to each other to allow the Controlling the DC power supply via the common node and the system load selectivity; a first switch connected to the second path allows the battery to selectively connect with the common node; and a comparator circuit and an output The wake-up circuit of the decision circuit. The comparison circuit is adapted to receive a first signal of a predetermined charging current and a second signal of a predetermined charging current supplied to the battery via the second impurity, and the comparison circuit Reacting the first and second signals to provide a comparison output signal. The output decision circuit is adapted to receive at least the comparison output signal and a selector signal from a selector circuit. The output determination circuit provides the comparison output signal And one of the selector signals, thereby controlling a state of the second switch. σ... The present invention also provides a new method for charging a battery, which is more efficient. In general, a wake-up circuit (such as the wake-up circuit 1608 shown in Figure 17) can receive a "wake-up program," (wake_up pr〇g) signal that represents a wake-up current value. Typically, the battery is provided. The wake-up current is a constant current value lwk〇, and the value is determined by the voltage value of the “wake-up program” signal. Since the wake-up charging process can be only the first part of the battery charging process, until the battery voltage exceeds one The preset voltage threshold value 'this total charging time is directly dependent on the time required for the wake-up charging process, that is, the voltage of a deep discharge battery rises from an initial value Vbatto to the wake-up threshold voltage The time required for Vwkth. The voltage Vbatto of a deeply discharged battery can be lower than any value of vwkth. For the sake of simplicity, the lowest possible value is 〇V. Since the charging time is a power supply An important performance parameter for managing the topology architecture, the wake-up charging time as part of the total charging time of the battery must be as short as possible. The wake-up current value lwk〇 should be programmed at the highest allowable value. Limiting the maximum value of the wake-up current can be different from the different factors' but the most important factors are as follows: @a battery-related limit ( Here, it can be expressed by limiting a battery's maximum 26 wake-up current lwkmb), mainly for battery characteristics, such as chemical composition and battery size, etc., such factors are determined by the battery manufacturer; c^ a limitation on power consumption ( Here, it can be represented by * table large wake-up current Iwkmp which limits power consumption, mainly for a current flow control device (CFCD) responsible for driving the charging current to the battery (for example, as shown in the embodiment of FIG. 17). The maximum power consumption Pm supported by the transistor SW2A1) Fig. 18A is a simplified mode of the power consumption pwk calculation when the current flow control device CFCD drives a constant current lwko during the wake-up charging process. Vadwk is a fixed-value DC output voltage provided by the power supply during the wake-up charging process. In order to ensure the flow of the wake-up current lwko, it is necessary to set The value of the Vadwk is slightly higher than the maximum battery voltage during charging in the awake mode (wake-up battery voltage threshold, Vwkth) (generally higher than 〇. 2 to 0.4 volts), that is, Vadwk = Vwkth + (〇. 2 〜0· 4 V). When the battery voltage is an instantaneous value Vbatt, the instantaneous power consumption amount Pwk of the current control device CFCD satisfies the following equation (1):

Pwk = lwko * (Vadwk - Vbatt) (1) Fig. 18B is a graph showing the power consumption pwk of the CFCD calculated according to the equation (i) as a function of the battery voltage Vbatt. It is obvious that the battery has the lowest voltage and the power consumption is the largest, and in fact the lowest battery voltage can be 〇V. When calculating the maximum wake-up current value lwkmp of the power consumption limit, the worst case of Vbatt, 0 should be considered, and the relative power consumption should be equal to the maximum allowable power consumption of the CFCD, i.e., pm. Therefore, in equation (1), if Pm is used instead of Pwk, lwkmp is used instead of lwko and Vbatt = 0, the maximum wake-up current lwkmp of power consumption limit is obtained: lwkmp = Pm/Vadwk (2) Gate in many instances' The limitation of lwkmp caused by the power consumption is added to the maximum settable wake-up current lwk〇, which is stricter than the relevant limitation of the battery type, that is, the equation (2) The lWkmp is much smaller than IwJyjjb. For example, for a current control device with Pm = 丨 · 2W and 27 1332302 2t, a fixed-value DC power supply with VadWk = 1GV (usually the voltage of the battery pack in series with three batteries can be 1 volt) The lwkmp given by the equation will be 120 mA, and the maximum power-on limit of the battery surface can be 3 〇〇 to 400 mA.

However, if the fixed-value wake-up current lwk0 is set to its power limit value (ie, 12 (M) in the above example, it will cause - long_dumping charge =, performance is degraded. Meanwhile, refer to equation (2), if ΐΛρ The limit value k is promoted to lwkmb. It is a power-saving, which is several times higher. (10) It is not cost-effective to use this high-power device, and the relative high power consumption will also reduce the wake-up. The efficiency of charging. Therefore, there is a need in the art for a more advanced method and circuit that can maintain a shorter wake-up charge while using a relatively low power CFCD while Fig. 19A and Figure 19B discloses the principle of the method for controlling a wake-up current according to the present invention. Figure 19A is a graph of a variable wake-up current iwk as a function of the instantaneous battery voltage. Figure 19B discloses a curve of the power consumption pwk of a CFCD as a function of the same battery voltage Vbatt. In this new method, the present invention uses a

The wake-up current lwk according to the battery voltage is substituted for the set value wake-up current lwk〇, as shown in the following equation (3): lwk - lwkmin + K * Vbatt (3) The wake-up current lwk has one at the lowest battery voltage Minimum value (assuming the battery, the low value of the voltage is 〇V, this minimum is lwkmin), as shown in Figure A, when the battery voltage is lower than Vbattl (when the wake-up current reaches the maximum wake-up current value Iwkmb of the battery limit) When the battery voltage is increased, the wake-up current iwk also increases linearly with a constant number of κ. The power consumption of the CFCD can be expressed as: ", '

Pwk = (lvwmin + K*Vbatt) (Vadwk - Vbatt) (4) Equation (4) is equivalent to Equation (1), and is replaced by the variable wake-up power IL in Equation (3) The fixed value wakes up the current lwko. 28 1332302, too fresh inspection can be Wei, such as (10) 槪, mm4) = power consumption voltage

Pwk has a maximum value Pwkmax whose value depends on both the = wake current value lwkrain and the value of the constant coefficient κ. , , § Λ , ^ Inductive charging method for the head 19 Α and Figure 19 This power consumption curve proposes two conditions H Du Ding electric grab and the process of the financial battery t test charge is too large; Say = wake up, the voltage inside the enclosure needs to have a current that limits the power consumption in the constant current method, (ie, toe > high tilt current has excellent mathematics that can check the wake-up charging time) The method can find a plurality of related lwk- values and K values to satisfy the above two conditions. Looking at the tilting charging method of the real money, the wake-up current of the second power cable PnH. 2W is driven by (10), - One output voltage of the DC power supply VadwHG Volt' If lwkmin is set to 8 (Μ, the value of the number of turns is set to K = 30 mA / V, $ is assumed to be called the Vwk system. 6 volts, according to etc. Equation (3) *(4), the wake-up current is linearly increased from 80 mA to 368 mA when charged to 9.6 volts, and the power consumption reaches a peak value of 12 w at a voltage of Vbatt = 3.7 volts. From this battery voltage, Vbatt = l · At the beginning of 33 volts, the value of the wake-up current will be greater than lwkmp = 120mA, which is the The value wakes up the power consumption limiting current in the current charging side. Compared with the charging method using the one value wake-up current lwk〇, the wake-up current lwko is again reduced to the power during the entire wake-up charging process. The limit value lwkmp=120 niA, and the new method provided by the present invention provides a variable wake-up current greater than 120 mA in almost the entire battery wake-up voltage range, thereby reducing the wake-up charging time. 29 The wake-up charging method provided by the present invention Another characteristic is that when the wake up level of the equation (3) exceeds the settable value, the SI current can be mismatched within a settable value (for example The battery-like wake-up current value Iwkmb). The examples of Figures 19A and 19B also disclose the case of assuming that the battery voltage exceeds Vbattl. Another embodiment of the present invention provides a variable wake-up current value (WL) electrical circuit. A variable charging current output signal representative of a battery can be provided, the charging method of which is consistent with the above new method. FIG. 2 is a variable wake-up current value WL circuit provided by the present invention. A typical embodiment of 2000.

The WL circuit 2000 includes an addition circuit 2〇〇1 and a comparison circuit 2002. It will be apparent to those skilled in the art that the operational amplifier AMP 2004 and the plurality of resistors R1 2006, R2 2008, R3 2012, R4 2014 and Rs 2010 can be operated as shown in FIG. It will be apparent to those skilled in the art that the output voltage Viwk of the summing circuit 2〇〇1 is a linear combination of the two voltages of Viwkmin and Vbatt, which are respectively transmitted through the resistor and input to the operational amplifier 2〇. The non-inverting input terminal (+ terminal) of 〇4 serves as an addition node of the adding circuit. The output voltage of the summing circuit 2001 is then in the form of:

Viwk = a*Viwkmin + b^Vbatt (5) If let P = (R3+R4)/R4, let RP = l/(i/Ri+1/R2+1/Rs), then equation (5) can be written as :

Viwk = (p*Rp/Rl) *Viwkmin +(p*Rp/R2)*Vbatt (6) Obviously, the coefficient in the equation (5), ie the coefficient & = (p*Rp)/Rl, coefficient &; = (p*Rp)/R2 'The coefficients a and b then only depend on the resistance of the selected resistors ri, R2, R3, R4 and Rs. Moreover, the selected resistance value can be selected as a = 1, b = K * Γ, where r is a settable ratio of the representative voltage to the relative representative current, and K is the equation (3) Constant coefficient (factor). In this example, if viwkmin is the voltage representing the 30th minimum wake-up current Iwkmin in equation (3), the output voltage Viwk of the adder circuit will represent the one shown in the equation (3). The variable wake-up current value is Chen. The signal Viwmiri can be externally transmitted to the WL circuit (as shown in FIG. 2A), can be internally generated and set by a common circuit of the WL circuit to be a combined estimate. Referring again to the embodiment of Fig. 20, the comparison circuit 2〇〇2 may include a comparator COMP 2016 including a switch drive circuit SDC MN and switches SW1 2G2G and SW2 2G22. The comparator 2016 will add circuit 2001

The provided signal Viwk is compared with a settable fixed value signal viwkff1, 1 table-maximum wake-up current lwkm' and delivers a digital output signal compout. The maximum wake-up current lwkm may be determined by any limiter other than the power consumption of the CFCD, for example, lwkm may be equal to the maximum wake-up current switch drive circuit 2〇18 of the battery limit, by Viwk When the switch is smaller than Viwkm, the switch SW1 is closed and the switch SW2 is turned off. When the Viwk is greater than Viwkm, the switch SW1 is kept open and the switch SW2 is closed to reflect the digital input recommended by the comparator. c^npout. Therefore, the value of the output signal 'wk-up prog' of the variable wake-up current value circuit 2〇〇〇 is equal to the viwk or the Viwkm ^

The smaller of the values. It should be noted that the switch SW1 and the SW2 in FIG. 20 can be selected from any suitable transistor, including a bipolar transistor and a field effect transistor. It will be apparent to those skilled in the art that the switch drive circuit 2〇18 is easy to implement, such as using suitable logic gates and lev shifters that enable the above functions. The present invention also provides a wake-up charging electric axis variable tilt current circuit (VWUG) capable of at least controlling the supply of a battery to a new method. Figure 21 is an exemplary embodiment 3000 of a variable wake-up current circuit of the present invention. This variable wake-up current circuit can be inserted into a power management topology similar to that shown in FIG. For simplicity, only the components associated with the function of the wake-up current circuit of Figure 31 can be depicted in FIG. In the embodiment shown in FIG. 21, the variable wake-up current circuit 21A includes a variable wake-up current value WL circuit 2000, an error amplifier 1610, and an output decision circuit 1612 (also referred to as a drive circuit). ). The architecture and function of the WL circuit 2000 is as previously described herein. The circuit provides a variable "wake-up" signal that represents a variable wake-up charge current supplied to battery Batt.A through switch SW2A1 (here as a CFCD). The voltage value of the "wake-up program" signal is linearly increased with the constant voltage coefficient Vbatt, and the value of the constant coefficient can be completely selected by selecting the resistor R1, 1^ in the chirp circuit 2000. 2, 1{3, [{4 and 1^ of this resistance value can be set. The voltage value of the "wake-up program" signal has a minimum value Viwkmin (which can also be set in the circuit 2000) when the battery voltage is one volt volt. At the same time, the signal Viwkm is limited to a maximum value setting. Thus, the signal viwkm is provided via the main interface 13 in an embodiment. The "wake-up mode" signal is also provided to the non-inverting input of the error amplifier 1610. The inverting input of the error amplifier 1610 receives a 丨CDA signal from a current sense amplifier (not shown in Figure 21) that represents the instantaneous charging current supplied to the battery. The error amplifier 161 and the operation mode of the & singularity decision circuit 1612 are identical to the error amplifier and the output decision circuit of the wake-up circuit 丨6 〇 8 = described in FIG. 17, and no longer, It should be noted that the methods described herein or the circuits implemented by the methods can be used alone, in conjunction with other battery charging methods or circuits, or as part of a broader battery charging method or circuit. It should be noted that the functions of the power management control circuit and the wake-up circuit described in this embodiment can also be implemented by using software or combining hardware and software. If μ is implemented in software, then it needs to be processed || and machine-readable.
