Abstract
Circuitry for powering a load and charging of a battery from a power source by a smart power supply is provided. The smart power supply controls the maximum current for battery charging based in part upon variables such as the maximum rate of charge of the battery and maximum source current. The smart power supply is thus capable of providing the power requested by the load, and use the remaining power for battery charging.
