S-82P1B Series www.ablic.com BATTERY PROTECTION IC FOR 1-CELL PACK ABLIC Inc., 2021 Rev.1.0 00 The S-82P1B Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. By using an external overcurrent detection resistor, the S-82P1B Series realizes high-accuracy overcurrent protection with less effect from temperature change. Features High-accuracy voltage detection circuit Overcharge detection voltage 3.500 V to 4.800 V (5 mV step) Accuracy 15 mV *1 Overcharge release voltage 3.100 V to 4.800 V Accuracy 50 mV Overdischarge detection voltage 2.000 V to 3.000 V (10 mV step) Accuracy 50 mV *2 Overdischarge release voltage 2.000 V to 3.400 V Accuracy 75 mV Discharge overcurrent detection voltage 1 3 mV to 100 mV (0.25 mV step) Accuracy 0.75 mV Discharge overcurrent detection voltage 2 6 mV to 100 mV (0.5 mV step) Accuracy 2 mV Load short-circuiting detection voltage 20 mV to 100 mV (1 mV step) Accuracy 5 mV Charge overcurrent detection voltage 100 mV to 3 mV (0.25 mV step) Accuracy 0.75 mV Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
