Pin Symbol Description 1 VCC Input Supply Voltage. Provides power to the charger. This pin should be bypassed with at least a 4.7 mF ceramic capacitor to ground. 2 FAULT An open−drain output indicating fault status. This pin is pulled LOW under any fault conditions. A FAULT condition resets the counter. 3 CFLG An open−drain output indicating charging or .
