Detailed description.
As shown in Figure 1, a kind of battery Zero consumption standby circuit provided by the utility model, including common end 1-6, resistance
R2, switching tube Q1, switch S1 and switching tube Q2, switching tube Q1 include the first control terminal 11, the output of first input end 13 and first
End 12, switching tube Q2 include that the second control terminal 21, the second input terminal 22 and second output terminal 23, resistance R2 are set to common end 1
Between the second input terminal 22, switch S1 is set between the first control terminal 11 and common end 6；
First control terminal 11 is connected to the second input terminal 22, and first input end 13 is connected to common end 5, the first output end 12
It is connected to common end 1；Second output terminal 23 is connected to common end 2, and the second control terminal 21 is connected to common end 3；
Common end 1 and common end 2 are respectively used to the power end of external power supply；Common end 5 and common end 6 are respectively used to external
The anode and cathode of MCU, common end 3 are used for the output end of external MCU, and common end 4 is used for the input terminal of external MCU；Common end 4
It is arranged between common end 5 and common end 6.
As shown in Fig. 2, this circuit is arranged in electronic product, when the electronic product needs to keep standby mode, open
It is in the open state to close S1, at this time due to having the presence of resistance R2, switching tube Q1 that can not be connected, therefore common end 5 and public affairs
6 no-voltages, MCU are held to can not work normally due to not having voltage altogether, the output of MCU is in low level state so that switch
Pipe Q2 is disconnected, and resistance R2 loses voltage, and since resistance R2 is in parallel with the control terminal 11 of switching tube Q1, i.e., the first control terminal 11 is also lost
Voltage is removed, further Q1 is prevented to be connected.When needing electronic product to work, by lower switch S1, it is closed in a flash in switch S1,
