BATTERY PROTECTION IC
WITH CHARGE-DISCHARGE CONTROL FUNCTION FOR 1-CELL PACK
Rev.1.2_01
The S-82B1A 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.
The S-82B1A Series has an input pin for charge-discharge control signal, allowing for charge-discharge control with an
external signal.
