Abstract: A battery charger includes a battery power regulator configured to set a charge signal provided to a battery based on a charge control signal and charge enable signal. The battery charger also includes a controller configured to provide the charge control signal to the battery power regulator. The controller is also configured to temporarily de-assert the charge enable signal for a predetermined amount of time in response to determining that a change is needed in the charge control signal. The controller is further configured to re-assert the charge enable signal after the predetermined amount of time.
