ABLIC S-82K1BAD-I6T1U

The S-82K1B 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-82K1B Series realizes high-accuracy overcurrent protection with less effect from temperature change.
