The S-8269B Series is an overcurrent monitoring IC for multi-serial-cell pack including high-accuracy voltage detection circuits and delay circuits.
By using an external overcurrent detection resistor, the S-8269B Series realizes high-accuracy overcurrent protection with less effect from temperature change.
The S-8269A series with CTL pin is also available. For details, please contact our sales offices.
