Rev.2.3_00 This IC 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 2-serial-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. Use of an external overcurrent detection resistor enables this IC to provide high-accuracy overcurrent protection with less impact from temperature changes. The S-82B2A Series has an input pin for charge-discharge control signal (CTL pin), allowing for charge-discharge control with an external signal.
