BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.2.1_01
The S-82A1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and 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-82A1A Series realizes high-accuracy overcurrent protection with less effect from temperature change.
