Features of S-82M1A/N1A/N1B Series. Contributes to longer battery life and higher safety.The S-82M1A 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-82M1A 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 4.600 V (5 mV step) Accuracy ±15 mV
Overcharge release voltage: 3.100 V to 4.600 V*1 Accuracy ±50 mV
Overdischarge detection voltage: 2.000 V to 3.000 V (10 mV step) Accuracy ±50 mV
Overdischarge release voltage: 2.000 V to 3.400 V*2 Accuracy ±100 mV
Discharge overcurrent detection voltage: 0.003 V to 0.100 V (1 mV step) Accuracy ±3 mV
Load short-circuiting detection voltage: 0.010 V to 0.200 V (1 mV step) Accuracy ±7 mV
Charge overcurrent detection voltage: −0.100 V to −0.003 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
