HSNT-8(1616) (PY008-A)
The S-82D1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes temperature protection circuits, high-accuracy voltage detection circuits, and delay circuits.
Temperature protection is possible by connecting an NTC thermistor to the dedicated connection pin.
It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.

*1. Temperature detection accuracy varies with NTC thermistor specifications.
When an NTC thermistor listed in Table 6 of the datasheet 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.)
