CW1013 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, it realizes high accuracy overcurrent protection with less effect from temperature change.
