Battery Protection IC with Battery Voltage Monitoring Pin for 1-Cell Pack S-82S1A Series

Resistance between BS pin and VSS pin: 5kΩ typ. (S-82R1A)  |  50Ω typ. (S-82S1A)
Battery Protection IC with Battery Voltage Monitoring Pin for 1-Cell Pack S-82S1A Series feature

This IC 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.
Overheat protection is possible by connecting an NTC thermistor to the NTC thermistor connection pin (TH pin.)
The battery voltage monitoring pin (BS pin) enables accurate voltage monitoring.

*1. Temperature detection accuracy varies with NTC thermistor specifications.
When an NTC thermistor listed in Table 5 is connected, the detection temperature and accuracy can be achieved.

*2. 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.)

*3. 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
