Abstract
A power supply covering power sharing and overshoot preventing functions. In the power supply, a first eFuse is used to deliver a first input power source to a first load at a first bus terminal, and a second eFuse is used to deliver a second input power source to a second load at a second bus terminal. When the current flowing through one eFuse hits its current limit threshold, the other input power source kicks in to provide power support. The current limit threshold of each eFuse is set to be lower than its maximum rated current.
