Abstract
Devices and methods for sharing power between power sources are disclosed. The power sources may be internal to an electronic device, external to the electronic device, or both. An electronic device may include a power source, a switch circuit, a processor, and a power management integrated circuit (PMIC). The processor may determine a load current estimate. The load current estimate may be based on a device setting, an external temperature, or both. The processor may determine a power source voltage, an external power source voltage, or both. The processor may determine a power source current, an external power source current, or both. The PMIC may set an output power source current of the power source. The PMIC may set an output external power source current of the external power source.
