Below according to optional embodiment of the invention, the present invention is described in detail：
The circuit system of the switch control rule of this alternative embodiment is by control unit, main control chip, power management chip, power supply
Battery, toggle switch composition.Toggle switch is struck and realizes the switching on and shutting down of terminal.Main control chip, power management chip,
Control unit constitutes a backfeed loop, and control unit tells power management chip according to toggle switch condition adjudgement result,
Power management chip is made whether the flow process of switching on and shutting down, and notifies main control chip, and main control chip again feeds back switching on and shutting down result
It is that next switching on and shutting down flow process is ready to control unit.Toggle switch is struck again to shutdown position, main control chip inspection
This state is measured, starts shutdown process, and notify that power management chip walks shutdown process, flow process to be shut down is completed, control
Unit cut-out battery processed and power management chip.When occurring when crashing, stir toggle switch and put off-mode, control unit
Cut-out battery and power management chip, release deadlock state, then stir toggle switch and put open state, you can start, real
Now reset and restart.
Optionally, toggle switch is directly connected to control unit and battery, and control unit is connected with power management chip, electricity

Show that the hardware components of circuit include two bleeder circuits, respectively the first bleeder circuit 50 and the second bleeder circuit 51, one
Individual charge-discharge circuit 52, a detection circuit 53, a toggle switch 54, a NPN triode 55, a time delay
Circuit 56, a negater circuit 57, a PMOS 58.
Fig. 6 is the sequential chart according to the change of the circuit level of alternative embodiment of the present invention, as shown in fig. 6, with reference to figure
6 come illustrate control unit realize function, when mobile terminal be in off-mode, at this moment start shooting detection signal (ON) be
Height, when user pushes open state toggle switch, cell voltage (VBAT) is changed into high, and charge-discharge circuit U1 is changed into
Height, the first bleeder circuit voltage U2 is changed into high, triode ON, and the second bleeder circuit voltage C outputs are uprised, reversely
Circuit output is low, PMOS conducting, while detection signal (ON) of starting shooting is pulled low, power management chip detection
It is low to start detection signal (ON), triggers power-on event, mobile terminal-opening, power management chip output signal
(LDO11) it is height.After the completion of start, U1 step-downs, U2 step-downs, triode cut-off, start detection signal (ON)
It is released as height.If user will shut down, toggle switch is allocated to into off-mode, shutdown detection signal (DET) is drawn
Low, it is low that main control chip detects shutdown detection signal (DET), triggers shutdown event, and mobile terminal shutdown is waited to close
Machine flow process is finished, and C signal is changed into low, and negater circuit is output as height, PMOS cut-off, system voltage (VPH_PWR)
For 0.When crashing, stir toggle switch and put shutdown position, C signal is changed into low, and negater circuit is output as height,
PMOS is ended, and system voltage (VPH_PWR) is 0, and toggle switch is stirred again to open state, it is possible to
Normal boot-strap, realizes crash reset and restarts.
When user stirs toggle switch to position of starting shooting, cell voltage (VBAT) representative value is 4V, and charge-discharge circuit is opened
Beginning charging process, the voltage of U1 begins to ramp up, and through a point first volt circuit partial pressure, U2 voltages begin to ramp up, more than three
The conducting voltage of pole pipe, triode ON, start detection signal (ON) is pulled low, while C point voltages are height, instead
To circuit turn-on, PMOS conducting, battery is to system power supply, triggering start.Then C1 starts electric discharge, U1 voltages
Decline, through the first bleeder circuit partial pressure, U2 voltages decline, less than the conducting voltage of triode, triode ends,
Start detection signal (ON) is driven high, and power management chip output signal (LDO11) is driven high, and completes one and opens
Machine process.When user stirs toggle switch to position of shutting down, shutdown detection signal (DET) is pulled low, main control chip inspection
It is low to measure shutdown detection signal (DET), starts to walk shutdown process, after software completes shutdown process, C point voltages
For low, negater circuit cut-off, PMOS cut-off, voltage (SYS_PWR) cut-off between battery and system.When
Crash, stir toggle switch and put shutdown position, C signal is changed into low, and negater circuit is output as height, PMOS
Cut-off, system voltage (VPH_PWR) is 0, realizes system power failure, and toggle switch is stirred again to open state,
Just can realize crash reset and restart with normal boot-strap.
Fig. 7 is the schematic diagram according to the main control chip of alternative embodiment of the present invention and the switching on and shutting down flow process of power management chip,
As shown in fig. 7, comprises：
S701, start detection signal puts height；
S702, stirs toggle switch；When toggle switch is stirred to start position, S703 is performed, opened when dial-up ought be stirred
During shutdown position, S705 is performed；
S703, start detection signal is dragged down；
S704, start, start detection signal is released, and power management chip output signal puts height；
S705, shutdown detection signal is pulled low；
S706, shutdown, battery and system voltage separate, and system voltage is 0.
When user stirs toggle switch to open state, U2 voltages are raised, triode ON, start detection signal (ON)
It is pulled low, power management chip detects start detection signal (ON) and is pulled low, while C point voltages are height, reversely
Circuit, PMOS conducting, battery to system power supply, triggering start, after the completion of start, believe by power management chip output
Number (LDO11) is driven high, and at this moment U2 voltages decline, and triode cut-off, start detection signal (ON) is released,
Complete a starting procedure.When user stir toggle switch to close when, shutdown detection signal (DET) be pulled low, master control
Chip detection starts to start shutdown process to after this state, after software completes shutdown, C point voltage step-downs, reversely
Circuit, PMOS cut-off, battery and system voltage (VPH_PWR) separate, system voltage (VPH_PWR)
For 0.When crashing, stir toggle switch and put shutdown position, C signal is changed into low, and negater circuit is output as height,
PMOS is ended, and system voltage (VPH_PWR) is 0, realizes system power failure, and toggle switch is stirred again extremely
Open state, it is possible to normal boot-strap, realizes crash reset and restarts.
Software control part is pulled low when power management chip detects start detection signal (ON), starts starting procedure,
Software is obtained after startup notifying, and boot animation is shown on screen.When main control chip detects shutdown detection signal (DET)
It is pulled low, software is obtained after shutdown notice, starts shutdown process, shutdown animation is shown on screen.
According to the starting up of terminal control circuit and method of above-mentioned alternative embodiment, compact brief with circuit design,
Function-stable, coordinate software, solve traditional touch-tone switching on and shutting down scheme need it is bad by power key Consumer's Experience with the head of a household
Problem, and realize the function that crash reset is restarted, reduce a reset and restart button, reduce terminal into
This.
