The S-8230A/B Series is a protection IC for 1-cell lithium-ion / lithium polymer rechargeable batteries and includes
high-accuracy voltage detection circuits and delay circuits.
The S-8230A/B Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from
overcharge, overdischarge, overcurrent, and controlling discharge by external signal.

*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV step.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV step.)
