ABLIC S-8252AAH-M6T1U

The S-8252 series incorporates a high-precision voltage detection circuit and delay circuit, serving as a protection IC for 2-cell series-connected lithium-ion/lithium-polymer rechargeable batteries. The S-8252 series is ideally suited for protecting 2-cell series-connected lithium-ion/lithium-polymer rechargeable battery packs against overcharge, overdischarge, and overcurrent.
