Temperature protection ensures safety of battery-powered devices
- Charge-discharge operations are performed within an appropriate temperature range
to enable the configuration of safer protection circuits. - Its low current consumption of 0.1μA max. during power saving
helps reduce standby current during warehousing and long-term storage. - Few external parts and a small package
shrink the size of the protection circuit board.

Improves safety through a temperature protection function
and shrinks protection circuit board size! 4 / 5-cell battery protection IC
Charge-discharge operation within appropriate temperature range
The S-82C4/C5 Series provides a temperature protection function and the connection of a single NTC enables 2-temperature (high and low temperature) monitoring during charging and discharging.
4-temperature monitoring enabled
- High temperature charge-discharge inhibition temperature
- High temperature charge inhibition temperature
- Low temperature charge inhibition temperature
- Low temperature charge-discharge inhibition temperature
The intermittent operation of the temperature detection circuit permits low current consumption even when using a 10kΩ NTC.
Contributing to lowering standby current during warehousing and long-term storage
The S-82B4/5 and 82C4/5 Series activate their power-saving functions through input of an external signal to the PSI pin to lower current consumption to 0.1µA max. (low current consumption mode).
Engage this mode prior to shipment to prevent loss of battery pack capacity from standby current during warehousing.
This also helps lowering standby current during long-term storage of devices.
Shrinking size of protection circuit boards
The S-82B4/5 and 82C4/5 Series have been tailored to the protection of 4-cell and 5-cell battery packs and have 25 to 40% fewer external parts than our previous products.
Use of a 16-pin TSSOP (6.4 × 5.1 × t1.1 (max.) mm), the industry’s smallest class of package*, has reduced the size of the protection circuit board.
As a 4 / 5-cell battery protection IC.
