S-82A1A Series www.ablic.com BATTERY PROTECTION IC FOR 1-CELL PACK ABLIC Inc., 2016-2019 Rev.2.4 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 3.5 V to 4.6 V (5 mV step) Accuracy 20 mV *1 Overcharge release voltage 3.1 V to 4.6 V Accuracy 50 mV Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy 50 mV *2 Overdischarge release voltage 2.0 V to 3.4 V Accuracy 100 mV Discharge overcurrent detection voltage 1 0.010 V to 0.100 V (1 mV step) Accuracy 3 mV Discharge overcurrent detection voltage 2 0.030 V to 0.200 V (1 mV step) Accuracy 5 mV Load short-circuiting detection voltage 0.050 V to 0.500 V (5 mV step) Accuracy 20 mV Charge overcurrent detection voltage 0.100 V to 0.010 V (1 mV step) Accuracy 3 mV Detection delay times are generated only by an internal circuit (external capacitors are unnecessary). 0 V battery charge: Enabled, inhibited Power-down function: Available, unavailable Release condition of discharge overcurrent status: Load disconnection, charger connection Release voltage of discharge overcurrent status: Discharge overcurrent detection voltage 1 (VDIOV1), discharge overcurrent release voltage (VRIOV) = VDD 0.8 (typ.) High-withstand voltage: VM pin and CO pin: Absolute maximum rating 28 V Wide operation temperature range: Ta = 40C to +85C Low current consumption During operation: 2.0 A typ., 4.0 A max. (Ta = +25C) During power-down: 50 nA max. (Ta = +25C) During overdischarge: 500 nA max. (Ta = +25C) *3 Lead-free, Sn 100%, halogen-free P *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.) *3.
