S-82F1B

S-82F1B Series www.ablic.com © ABLIC Inc., 2017-2018 BATTERY PROTECTION IC FOR 1-CELL PACK Rev.3.1_00 The S-82F1B Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and 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-82F1B Series realizes high-accuracy overcurrent protection with less effect from temperature change.  Features High-accuracy voltage detection circuit Overcharge detection voltage Overcharge release voltage 3.500 V to 4.600 V (5 mV step) 3.100 V to 4.600 V*1 Accuracy ±15 mV Accuracy ±50 mV Overdischarge detection voltage Overdischarge release voltage 2.000 V to 3.000 V (10 mV step) 2.000 V to 3.400 V*2 Accuracy ±50 mV Accuracy ±75 mV Discharge overcurrent detection voltage 1 0.003 V to 0.100 V (0.5 mV step) Accuracy ±1.5 mV Discharge overcurrent detection voltage 2 0.010 V to 0.100 V (1 mV step) Accuracy ±3 mV Load short-circuiting detection voltage 0.020 V to 0.100 V (1 mV step) Accuracy ±5 mV Charge overcurrent detection voltage −0.100 V to −0.003 V (0.5 mV step) Accuracy ±1.5 mV Detection delay times are generated only by an internal circuit (external capacitors are unnecessary) Discharge overcurrent control function Release condition of discharge overcurrent status: Load discon...
