This output connects to the gate of the discharge MOSFET allowing it to enable or disable
battery pack discharging.
This is the charger negative input pin. It connects to the excess current detectors and serves as
the common node for the CO pin during turn−off.
This output connects to the gate of the charge MOSFET switch allowing it to enable or disable
battery pack charging.
This is the delay time reduction pin.
This input connects to the positive terminal of the cell for voltage monitoring and provides
operating bias for the integrated circuit.
This is the ground pin of the IC.
