Abstract: A system for power management of an electronic device. The system comprises a programmable system microcontroller; power ports configured to sink or source electrical power; and a programmable power multiplexor connected between the power ports and the system microcontroller. The system further comprises bi-directional load switches connected between the power port and a bi-directional voltage convertor, and configurable to allow electrical power to flow through the bi-directional load switch. The bi-directional voltage convertor converts a first voltage supplied by the bi-directional load switch to a second voltage and supplies power at the second voltage to the electronic device or external device through the power ports. The programmable system microcontroller controls the direction in which each bi-directional load switch allows power to flow and the second voltage, such that the system sinks or sources power at each of the power ports according to programming of the system microcontroller.
