Abstract
An electronic device balances power supplied to a system load by a first battery power source and a second battery power source. A battery current sense circuit is electrically coupled to sense a first current supplied by the first battery power source to the system load. A discharge feedback controller is electrically coupled to the battery current sense circuit and configured to adjust a control voltage based on the sensed first current. A voltage converter circuit includes an input electrically coupled to the second battery power source and an output electrically coupled to the system load. The voltage converter circuit is configured to adjust current supplied by the second battery power source through the voltage converter circuit to the system load based on the control voltage.
