Current protection for battery charger
Abstract:
A device includes a battery current sense circuit configured to generate a battery current feedback voltage based on a current provided to a battery, a current regulation feedback loop configured to regulate the current provided to the battery based on the battery current feedback voltage and a configurable battery current reference voltage, and a precharge regulation feedback loop configured to regulate the current provided to the battery based on the battery current feedback voltage and a configurable precharge reference voltage. The device also includes a processor configured to set the battery current reference voltage to a first value and set the precharge current reference voltage to a second value. The first value is less than the second value during a transition state.
