ABLIC S-82H1AAH-A8T2U

The S-82H1A 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-82H1A Series realizes high-accuracy overcurrent protection with less effect from temperature change. The S-82H1A Series also has an input pin for charge-discharge control signal, allowing for charge-discharge control with an external signal.
