The second end and third end for closing T3 disconnect, i.e. charge switch T3 is off-state.
At this point, if the first end of power switch T2 is connected with the second end of power switch T2, the first of power switch T1
End is grounded by power switch T2, receives low voltage signal so as to the first end of power switch T1, then power switch T1 controls supply
The second end of electric switch T1 is connected with the third end of power switch T1, i.e. power switch T1 is in the conduction state.Thus with power supply
The governor circuit 20 that the third end of switch T1 is connected receives driving voltage V1 by power switch T1, so that governor circuit 20
It starts to work.
If the first end of power switch T2 is connected with the third end of power switch T2, the first end of power switch T1 passes through
Boost resistor R1 receives driving voltage V1, and the current potential of the first end of power switch T1 is pulled to high voltage, power switch T1 controls
The second end of power switch T1 processed is disconnected with the third end of power switch T1, i.e. power switch T1 is off.Thus with
The governor circuit 20 that the third end of power switch T1 is connected cannot receive driving voltage V1 by power switch T1 so that master control electricity
Road 20 is stopped.Meanwhile the first end of discharge resistance R2 is grounded by power switch T2, the second end of discharge resistance R2 and filter
The first end and governor circuit 20 of wave capacitance C1 is connected, then the energy-storage travelling wave tube on filter capacitor C1 and governor circuit 20 such as electricity
The charge of appearance, inductance etc. is discharged by discharge resistance R2, and governor circuit 20 is made to be stopped in time.
So when charging port stops receiving external voltage V2, charge switch T3 is off.It is meanwhile if electric
The first end of source switch T2 is connected with the second end of power switch T2, then governor circuit 20 receives driving voltage V1 and starts to work；
If the first end of power switch T2 is connected with the third end of power switch T2, governor circuit 20 stops receiving driving voltage
V1, and the charge of filter capacitor C1 and the energy-storage travelling wave tube on governor circuit 20 is discharged by discharge resistance R2, makes governor circuit 20
It is stopped in time.
In one embodiment, charge switch T3 is triode transistor, and the first end of charge switch T3 is base stage, and charging is opened
The second end for closing T3 is emitter, and charge switch T3 thirds end is collector.But the utility model is not limited thereto, and charging is opened
It closes T3 and can also be N-channel MOS transistor etc..
In one embodiment, charging port is USB interface, for receiving external voltage V2.But the utility model is not
As limit, such as charging port can be lightning interfaces etc..
The power control circuit 10 of the present embodiment when charging port receives external voltage V2, passes through the first divider resistance
R3 and the second divider resistance R4 are as divider resistance so that charge switch T3 is in the conduction state, and then power switch T1 is in
Conducting state, so as to which battery 30 receives the charging current of external voltage V2 and charges.Meanwhile charging port passes through the electricity that charges
Road 40 is connected with governor circuit 20, then the driving current of the reception external voltage of governor circuit 20 V2 works.
When charging port stops receiving external voltage V2, if the first end of power switch T2 and the second of power switch T2
End is connected, and governor circuit 20 receives driving voltage V1 and starts to work；If the of the first end of power switch T2 and power switch T2
Three ends are connected, and governor circuit 20 stops receiving driving voltage V1, and filter capacitor C1 and the energy-storage travelling wave tube on governor circuit 20
Charge is discharged by discharge resistance R2, and governor circuit 20 is made to be stopped in time.
