BATTERY PROTECTION IC
WITH DISCHARGE CONTROL FUNCTION FOR 1-CELL PACK
Rev.2.5_01
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.
Features
High-accuracy voltage detection circuit
Overcharge detection voltage
3.5 V to 4.5 V (5 mV step)
Accuracy 20 mV (Ta = 25°C)
Overcharge release voltage
3.1 V to 4.5 V*1
Accuracy 25 mV (Ta = 10°C to 60°C)
Accuracy 30 mV
Overdischarge detection voltage
Overdischarge release voltage
2.0 V to 3.4 V (10 mV step)
2.0 V to 3.4 V*2
Accuracy 35 mV
Accuracy 50 mV
Discharge overcurrent detection voltage 0.05 V to 0.20 V (10 mV step)
Accuracy 10 mV
Load short-circuiting detection voltage
0.5 V (fixed)
Accuracy 100 mV
Charge overcurrent detection voltage
0.20 V to 0.05 V (25 mV step) Accuracy 15 mV
0.16 V to 0.08 V (40 mV step)
Detection delay times are generated only by an internal circuit (External capacitors are unnecessary).
Accuracy 20%

*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.)
