When the battery voltage is detected to be higher than 104% typical of the battery charging regulation voltage, the charger turns off the converter to prevent the battery voltage from further increasing. When the battery voltage drops below 102% typical of the battery charging regulation voltage, the converter automatically restarts. The system load is supplied by battery through battery FET when the converter is disabled. A /INT pulse is asserted to alert the host if the VBAT_OVP_MASK is low and the VBAT_OVP_STAT and VBAT_OVP_FLAG register bits report the fault.
