Abstract: A power management system includes a plurality of inputs that may be coupled to a plurality of devices to receive power therefrom and a plurality of outputs that may be coupled to the plurality of devices to provide power thereto. A device may include a load and an internal power sources that may be used to power the load or may be coupled by the power management system to another device. Likewise, the load may receive power from another device. The power management system couples each input to one of the outputs. An output is selected for an input based on priorities associated with the outputs and inputs. Each input and output may be coupled to a power bus by a multiplexer such that each input may be coupled to any output by coupling both to a common bus line.
