Power management systems and methods for a mobile device
First Claim
1. A power management system for a mobile device, comprising:
- a primary power management circuit configured to receive an input voltage and use the input voltage to supply power to the mobile device;
a secondary power management circuit configured to select at least one of a battery signal 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 input voltage to the primary power management circuit being received by the primary power management circuit from the secondary power management circuit;
the primary power management circuit being further configured to use the first power source to charge the rechargeable battery; and
the secondary power management circuit being further configured to use the second power source input to charge the rechargeable battery.

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.
