1

The S-82A1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and 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-82A1A Series realizes high-accuracy overcurrent protection with

less effect from temperature change.
