FUNCTION

Power Supply Input. Connect this pin to external DC supply. Bypass to GND with a 1µF

(minimum) ceramic capacitor.

Ground terminal.

Provide an interval voltage divider. This pin divides ACIN voltage into 39/369 ratio.

Charging current control pin. When sourcing a current from this pin, the OUT pin will source

out a current whose magnitude is 200xIGATDRV .

Output Pin. The pin provides supply voltage to the PMIC input. Bypass to GND with a 1µF

(minimum) ceramic capacitor.

Output Pins. The pin provides supply source current in series with a resistor to battery.

This pin possesses the overshoot clamp function to limit peak voltage.

Exposed Thermal Pad. Must be electrically connected to the GND pin.
