The S-8211D 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-8211D Series is suitable for protecting 1-cell rechargeable lithium-ion / lithium-polymer battery packs from overcharge,
overdischarge, and overcurrent.
