            S-82A2/B2 Series 2-Cell Battery Protection ICs
                    ABLIC’s S-82A2/B2 series ICs are ideal for high-accuracy overcurrent protection and high safety
    

ABLIC’s S-82A2A/B/C and S-82B2A/B series 2-serial cell battery protection ICs use an external current sensing resistor to deliver high-accuracy overcurrent protection not easily susceptible to battery voltage and temperature fluctuations. The S-82A2A/B/C series features a protection IC that provides a charge/discharge overcurrent detection voltage accuracy of ±1 mV.

These 2-cell ICs contribute to better safety of small power tools, cordless cleaners, and other devices that use comparatively high current.
