BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.7.6
_00
The S-8211C Series is a protection IC for 1-cell lithium-ion / lithium polymer rechargeable battery and includes high-
accuracy voltage detection circuits and delay circuits.
The S-8211C Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from
overcharge, overdischarge, and overcurrent.
