The S-82M1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy

voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery

packs from overcharge, overdischarge, and overcurrent.

By using an external overcurrent detection resistor, the S-82M1A Series realizes high-accuracy overcurrent protection with

less effect from temperature change.
