When number invalid, then V makes battery output control signal high level by R112, R88, this high level can be considered control battery not to
Outer electric discharge.
When starting key is pressed, starting-up signal is low level short-circuit signal, controls Q26 by R309, R80 extremely low
Level shutdown, and then make V that Q34 control extremely high level be connected by R82, R83, and then keep battery output control signal low
Level；Whether run signal is effective at this time, i.e. whether Q27 is connected, and not influencing battery output control signal is low level；This low electricity
It is flat to can be considered that control battery discharges；After electronic equipment brings into operation, the run signal of high level is provided, is made by R86
Q27 control extremely high level is connected, and then makes battery output control signal low level；Whether starting-up signal is effective at this time, i.e.,
Whether Q34 is connected, and not influencing battery output control signal is low level；This low level we can be considered control battery put
Electricity.
And when starting-up signal, run signal are no longer valid, i.e. power button is not pressed, and electronic equipment does not provide
The run signal of high level, as previously mentioned, then V by R112, R88 make battery output control signal high level, this high level
We can be considered that control battery does not discharge outward.
As the variation of foregoing circuit, starting-up signal, run signal and battery output control signal can be according to circuit controls
Logic processed need for high level it is effective or low level is effective, it is only necessary to pass through and increase inverter cricuit in related circuit.
Electronic equipment is booted up or shut down generally by way of key, in one alternate embodiment, booting
Detection circuit includes: starting key detection circuit, and the power knob for detecting the electronic equipment being in the standby state is
It is no to be pressed.Detecting that starting key detection circuit judges that electronic equipment is triggered booting in the case where being pressed.
Above-mentioned booting detection circuit 11 can realize that Fig. 3 is according to an embodiment of the present invention opens by a variety of circuit forms
Machine testing examples of circuits figure, booting detection circuit 11 include: first resistor and second resistance, and first resistor and second resistance are distinguished

Resistance, the drain electrode of transistor are connected to second resistance, and the source electrode of transistor is connected to earthing potential；Capacitor is connected to transistor
Drain electrode and earthing potential；The anode of diode, the diode is connected to earthing potential, and the cathode of the diode is connected to crystal
The drain electrode of pipe, and export the first control signal.
In one alternate embodiment, closedown detection circuit 12 is connected to the standby power of electronic equipment, is detecting
When trigger signal of shutting down, the second control signal is exported.
The structure type of above-mentioned closedown detection circuit 12 also may include many kinds, in one alternate embodiment, shutdown
Detection circuit 12 includes: logical unit, is connected to standby power, is exported after carrying out logical operation to the level signal of input
Operation result；Rp unit is connected to the enable end of logical unit and battery control circuit, is used for logical unit
The operation result of output exports the second control signal after carrying out reverse phase processing.
In one alternate embodiment, logical unit include with door, rp unit includes phase inverter.
In conclusion electronic equipment may be implemented in battery protecting circuit through the embodiment of the present invention, battery is at work
Normal output state, battery closes corresponding output when equipment shutdown does not work, to avoid and reduce accordingly because electronics is set
For regardless of whether battery is in total power output state bring security risk and ageing equipment wind always in working condition
Danger.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
