BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.6.0
_00
The S-8211C Series are protection ICs for single-cell lithium-ion / lithium polymer rechargeable batteries and include high-
accuracy voltage detectors and delay circuits.
These ICs are suitable for protecting single-cell rechargeable lithium-ion / lithium polymer battery packs from overcharge,
overdischarge, and overcurrent.
