It is grounded by resistance R101, diode D101 positive pole meets power end VBAT, and negative pole is connected on diode D100 negative pole and charging
Between indicator lamp LED100.
In the present embodiment, switch Mos pipes Q100, Q101 model CJ4153, the diode D100, D101,
D102, D103 model B1045WS, the model A-SP194GHC-C01-3T of the charging indicator light LED100.
Charging stage, because of mobile phone brownout, system can not get up, and all of the port of cell phone mainboard chip can not all be controlled
System, it can only be controlled by partial circuit of the present utility model to realize.After mobile phone is connected to charger or computer by USB line,
5V voltages by diode D100 supply charging indicator light LED100, through current-limiting resistance R100 to switch mos pipes Q100 D poles,
Another routing resistance R102 of 5V voltages, after diode D103 and resistance R101 partial pressures, supply switch Mos pipes Q100 G poles,
Metal-oxide-semiconductor Q100 conductings are now switched, charging indicator light LED100 is lighted, and realizes that preliminary filling indicates.In such a mode, Mos pipes are switched
Q101, diode D102 are low because of control port Default.All it is off.Diode D101 is also because cathode voltage is higher than
VBAT and reversely end.
When charging normal, the mainboard chip of mobile phone can normally export corresponding voltage.When mobile phone is connected by USB line
After being connected to charger or computer, 5V voltages are supplied to switch Mos pipes Q101 D poles through diode D100, resistance R102 all the way, together
When cell phone mainboard chip GPIO interface LED_EN_2 output high level to switch Mos pipes Q101 G poles, switch Mos pipes Q101
Conducting.The path of 5V power supplys supply switch Mos pipe Q100 G pole tensions is switched on and off Mos pipes Q101 and dragged down, and have turned off by electric before
The controlling switch that road is formed.The another way of 5V voltages supplies charging indicator light LED100 by diode D100, through current-limiting resistance
R100 is to switch Mos pipes Q100 D poles, while cell phone mainboard chip GPIO interface LED_EN_1 outputs high point is put down, through diode
