ABLIC S-8240A Battery Protection ICs
ABLIC S-8240A Battery Protection ICs are for lithium-ion/lithium polymer rechargeable batteries. The ICs include high-accuracy voltage detection circuits and delay circuits. The S-8240A Series can protect 1-cell lithium-ion/lithium polymer rechargeable battery packs from overcharge, over-discharge, and overcurrent.
