Functions
Power supply
Detecting adapter output voltage and connecting capacitor for phase
compensation to the charge constant voltage control circuit
The ground pin for signal unit
Driving photo coupler for feedback (opened collector, including resistance
for pulled up)
Monitoring the battery voltage. Input the 1/3 battery voltage gained
differentially to control charge constant voltage and to detect each voltages.
Outputting the voltage gained differentially from the battery voltage
Detecting the battery connection and the battery temperature
Driving charge SW transistor (opened collector, including the circuit driving
the constant current)
The ground pin for the circuit generating the referential voltage to compare
with TH pin voltage
Detecting output current and connecting capacitor for phase compensation
to the charge constant current control circuit
Setting the current of over current. The referential voltage is decided by
dividing external resistances.
The ground pin for power unit
Setting frequency for inside clock by CR oscillator
Setting quick charge current. The referential voltage is decided by dividing
external resistances.
Setting trickle current. The referential voltage is decided by dividing external
resistances.
Setting the charge completion current. The referential voltage is decided by
dividing external resistances.
Detecting the connection of DC JACK. (including resistance for pulled up)
Switching charge mode
Driving LED (opened collector, including the circuit driving constant current)
Controlling the referential voltage
Providing the referential voltage
For inputting the charge constant voltage amp. and connecting capacitor for
phase compensation to the charge constant voltage control circuit
