Abstract: Methods of operating a power supply switching circuit including selecting a first power supply signal for provisioning through the power supply switching circuit to a electronic storage device. A current draw can be detected via the first power supply signal that exceeds a predetermined current limit and a second power supply signal can be coupled to the first power supply signal for provisioning through the power supply switching circuit to the electronic storage device responsive to the current draw exceeding the predetermined current limit.
