It is connected to the base stage of triode Q3 through resistance R4, triode Q3 is connected, triode Q3 emitter output high level is connected to three
The collector of pole pipe Q1 tends to remain on triode Q2, within a certain period of time, after capacitor C1 is fully charged, makes triode
Q1 cut-off, but at this point, being held on triode Q2 after triode Q3 conducting, relay J1 keeps attracting state, and mobile phone is kept
Charged state.
After mobile phone is fully charged, the pressure drop generated on the cathode of diode D3 and the resistance R5 of diode D3 parallel connection becomes
Small, because mobile phone electricity has been filled at this time, charging current becomes smaller, and ends triode Q4, capacitor C2 will pass through resistance R4 to three at this time
Pole pipe Q3 base stage is discharged to emitter, is held on triode Q3, is made mobile phone charging keep centainly being completely filled in electricity, is worked as electricity
After appearance C2 is discharged, triode Q3 cut-off, triode Q2 ends, and relay J1 power-off does not work, and J1-1 normally opened contact disconnects,
The end DC2 makes no longer to overcharge after hand self-contained battery is fully charged without 5V voltage output, so that hand self-contained battery be protected not overcharge, extends
The service life of lithium battery in mobile phone, and reached using electricity wisely.
