    Hey CQ.LV,

    The BQ25703A is a host-controlled charger, and thus the charge current and profile must be programmed via I2C by the host.

    In default mode, charging is disabled. The is the EN_AUTO_WAKEUP which is enabled by default, but this will only charge the battery up to the minimum system voltage with 128mA of current.

    Regards,
