ABLIC S-8252AAJ-M6T1U

The S-8252 series is a protection IC for 2-cell series-connected lithium-ion/lithium-polymer rechargeable batteries, integrating a high-accuracy voltage detection circuit and delay circuit. This series is designed to protect 2-cell series lithium-ion/lithium-polymer battery packs from overcharge, overdischarge, and overcurrent damage.
