Additional Details

The S-8261DAX-M6T1U incorporates features such as overcharge detection voltage, overdischarge detection voltage, and overcurrent detection current. The IC monitors the battery's voltage and current, and when a fault condition is detected, it takes action to protect the battery by disconnecting it from the charging or discharging circuit. The extremely low current consumption of the IC contributes to extending battery life in portable devices.

The device typically comes in a small package such as SOT-23-6, which allows for easy integration into space-constrained applications. For proper use, designers must refer to the datasheet for specific electrical characteristics, application circuits, and handling precautions. ABLIC also provides application notes and reference designs to assist in the implementation of the S-8261DAX-M6T1U in various applications.
