ABSTRACT:
Power management systems and methods are provided for a mobile device. A primary power management circuit may be configured to receive an input voltage and use the input voltage to supply power to the mobile device. A secondary power management circuit may be configured to select at least one of a battery input from a rechargeable battery, a first power source input, or a second power source input as the input voltage to the primary power management circuit. The primary power management circuit may use the first power source input to charge the rechargeable battery. The second power management circuit may use the second power source input to charge the rechargeable battery.
