Connecting display lamp LED1, LED2, MCU chip U1 chip U1 is also associated with resistance R7, R8, and electric capacity C1, C8, MCU chip U1 core
Sheet U1 is connected with Parallel Control circuit and series control circuit respectively by connecting end BL with QL.
After normally powering on, BL and the QL output low level of MCU chip U1, Q19, Q20, Q21, Q22 are cut-off state,
Metal-oxide-semiconductor Q1, Q2, Q3 are closed, set of cells BT1 negative pole be connected to GND by the diode within metal-oxide-semiconductor Q2, electricity
Pond group BT2 positive pole be connected to VDD by the diode within metal-oxide-semiconductor Q1, two set of cells lead to the pole, inside two of red Q1 Yu Q2
Guan Houcheng parallel connection, this state can be done small area analysis to system and power, but High-current output just has pressure drop, reason be Q1,
The internal body diodes of Q2 has 0.7V pressure drop, therefore is not suitable for High-current output.
When the BL of MCU chip U1 be high level, QL be low level time, Q19, Q20 turn on, and control signal leads to a liter piezoelectricity
Road, the rising of control signal voltage is exported on B1 by the element such as U2, L1, D5 composition booster circuit, and B1 signal divides 2 tunnels, a road
Through R3, R4 dividing potential drop rear drive Q2, Q2 is allowed to turn on, the most directly output of set of cells BT1；Another road is after D1, by R1, R2 dividing potential drop rear-guard
Dynamic Q1, allows Q1 turn on, in the most directly output of set of cells BT2, with BT1 composition Parallel opertation external equipment, and output voltage VDD warp
To the AD port of MCU chip U1 after R7, R8, C1 dividing potential drop, MCU chip U1 is sampled by AD just to measure and is exported the magnitude of voltage of VDD and sentence
Disconnected parallel connection switching is either with or without success, successful then LED1 length is bright；Such as handoff failure, BL output low level, LED1 is glittering, and circuit is described
Faulty.
Diode D1 is isolation Q1, Q2, because the positive pole being in BT2 of Q1, current potential is higher than Q2, additionally, due to metal-oxide-semiconductor
Characteristic, the MOS of N-type is less than the MOS internal resistance of p-type, and this programme is again the application exporting big electric current, and Q1 must use the MOS of N-type
Pipe, therefore if making Q1 conducting necessary, the voltage of control signal necessarily be greater than the voltage of VDD, therefore booster circuit to be used raises
The voltage of control signal, reaches to control the requirement of Q1.
When MCU chip U1 when the BL of MCU chip U1 be low level, QL be high level time, Q21, Q22 turn on, control signal
On D2 to R5, R6 bleeder circuit, then drive Q3 to turn on, the negative pole of the positive pole of set of cells BT2 Yu set of cells BT1 is connected to one
Rising, composition is after BT1 with BT2 connect, then exports output voltage VDD in external equipment and arrive MCU chip U1 after R7, R8, C1 dividing potential drop
AD port, MCU chip U1 sampled by AD just record the magnitude of voltage of output VDD judge series connection switching either with or without success, success
Then LED1 length is bright；Such as handoff failure, QL output low level, LED2 is glittering, illustrates that circuit is faulty.
Diode D1 described further is isolation control signal, prevents Q3 when closed, comes to control signal feed, dry
Disturb other element.
More preferably, as big in output electric current if, can be on Q1, Q2, Q3 and connect metal-oxide-semiconductor, to reduce internal resistance and to increase defeated
Go out electric current.
Above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not
Restriction to embodiment of the present utility model.And it is apparent for belong to that connotation of the present utility model extended out
Change or variation still fall within protection domain of the present utility model.
