How to terminate or set the termination current of the buck-boost chargers?

    Hi all,

    The buck-boost charger controller BQ25710, BQ25720 and BQ25730 is a host-controlled device. It doesn’t have a termination current setting and cannot terminate the charging by itself. After the charger enters CV (constant voltage) mode and charge current begins to tamper, the host (embedded controller) needs to monitor the battery conditions (voltage and charge current) and terminate by the host. This operation principle also applies to BQ25700A, BQ25703A,  BQ25708, BQ25713, BQ25713B, BQ25723, and BQ25731.

    Thanks and I hope this helps,

    Peng
