The new S-82D1A Series is a 1-cell lithium-ion battery protection IC providing (1) temperature protection in addition to common overcharge, overdischarge, and overcurrent protection functions. The temperature protection function monitors rises and falls in temperature to enable configuration of circuits providing even greater safety. (2) The charge and discharge control function uses external signals to prohibit battery pack charging and discharging. (3) The accuracy of overcharge detection voltage is as high as ±15mV, while current consumption during operation and protection is 5μA max., which ranks the industry’s top-class.

[Major Features]

1. The IC is resistant to noise, and possible to monitor four temperatures with the temperature protection function.

2. External signal input pin enables charge and discharge control

3. Overcharge detection voltage accuracy: ±15mV. High performance yet low current consumption of 5μA max.


• Lithium-ion rechargeable battery packs, lithium polymer rechargeable battery packs

[Application Examples]

Smartphone, Smartwatch, Headset, Tablet PC, Glass-like device, Activity monitor, Shaver
