ABLIC Inc. S82A2A/B/C and S-82B2A/B Series are the world’s first*
2-serial cell battery protection ICs using an external current detection resistor to deliver high-accuracy overcurrent protection not easily susceptible to battery voltage and temperature fluctuations. Moreover, the S-82A2A/B/C series comes with a protection IC whose charge/discharge overcurrent detection voltage accuracy of ±1mV places it in the industry’s high-accuracy top class.

In the S-82A2A/C and S-82B2A Series, an external input to the CTL (charge-discharge control signal input) pin activates the charge-discharge control function and disables battery charge and discharge. By connecting a PTC thermistor to the CTL pin, the IC delivers thermal protection by disabling charging and discharging of the battery pack at high temperatures.

In the S-82A2B and S-82B Series, an external input to the
PS (power-saving signal input) pin will activate the power-saving function and disable battery discharge. Simultaneously, the protection IC itself suppresses current consumption to 50nA max. This helps lowering battery consumption to virtually zero during long-term storage of devices, which contributes to reducing standby current.
