ABLIC S-82L1/T1/U1/V1 Battery Protection ICs

ABLIC S-82L1/T1/U1/V1 Battery Protection ICs monitor the voltage between V_DD and V_SS with high accuracy of ±12mV. The ABLIC S-82L1/T1/U1/V1 ICs overcome the difficulties posed by current detection resistance and FET on-resistance. The alarm signal output to the charge control circuit accurately detects the battery voltage, adjusting the current and charge voltage accordingly. This results in safe and efficient fast charging, improving device safety and extending battery life.

Features

Overcharge detection voltage accuracy of ±12mV maximizes battery performance
Overcurrent detection voltage accuracy of ±0.75mV suppresses heat generation in the protection circuit board
