Ground. VSS is the source of the internal Discharge MOSFET. Connect VSS directly to the
cathode of lithium-ion/lithium polymer battery cell.
Output Pin. OUTM is the source of the internal Charge MOSFET. Connect OUTM directly to the
negative terminal of the battery pack.
Over-current / Charger Detection Pin. Connect a 2kW resistor between VM and the negative
terminal of the battery pack.
Input Supply Pin. Connect a 0.1uF capacitor between VDD and VSS.
Discharge MOSFET Gate. This pad is for test purposes only. Always leave this pad unconnected.
MOSFET Common-Drain Connection. This pad is for test purposes only. Always leave this pad
unconnected.
