S-82A1A

S-82A1A Series www.sii-ic.com © SII Semiconductor Corporation, 2016 BATTERY PROTECTION IC FOR 1-CELL PACK Rev.2.0_00 The S-82A1A 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-82A1A Series realizes high-accuracy overcurrent protection with less effect from temperature change.  Features High-accuracy voltage detection circuit Overcharge detection voltage Overcharge release voltage 3.5 V to 4.6 V (5 mV step) 3.1 V to 4.6 V*1 Accuracy ±20 mV Accuracy ±50 mV Overdischarge detection voltage Overdischarge release voltage 2.0 V to 3.0 V (10 mV step) 2.0 V to 3.4 V*2 Accuracy ±50 mV Accuracy ±100 mV Discharge overcurrent detection voltage 1 0.010 V to 0.100 V (1 ...
