The S-8240A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy
voltage detection circuits and delay circuits.
The S-8240A Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge,
overdischarge, and overcurrent.
