描述

The ISL9301EVAL1Z is an evaluation board for the ISL9301 single-cell Li-ion battery charger. This tool provides a complete evaluation platform addressing all datasheet specifications and functionality. The jumpers on the board facilitate the programming of the charge current, different charging conditions, and can be used to make other necessary connections, such as current measurement.

The ISL9301 is an Li-ion battery charger with a power path management function. It uses separate power paths to supply the system load and charge the battery. This feature allows the system to immediately operate with a completely discharged battery and allows the charge to terminate when the battery is full while continuing to supply the system with the input source, thus minimizing unnecessary charge/discharge cycles and improving the battery life.
