Battery Protection IC for 1-Cell Pack S-82A1A Series

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
Overcharge release voltage 3.1 V to 4.6 V*1 Accuracy ±50 mV
Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy ±50 mV
Overdischarge release voltage 2.0 V to 3.4 V*2 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).

*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.)

Applications

  • Lithium-ion rechargeable battery pack
  • Lithium polymer rechargeable battery pack
