POWER SUPPLY SELECTOR AND METHOD FOR MINIMIZING AN INRUSH CURRENT IN A POWER SUPPLY SELECTOR |
摘要 |
A method for minimizing an inrush current in a power supply selector and a power supply selector system is provided. The power supply selector includes a plurality of power input nodes, a power output node, a first transistor and a second transistor. Each of the power input nodes may be coupled to a first switch having a first on-resistance and to a second switch having a second on-resistance. The second on-resistance is greater than the first on-resistance. The first switch and the second switch are preferably coupled in parallel. The power supply selector may be configured to couple a selected one of the power input nodes to the source of the first transistor and to the gate of the second transistor so as to sense a sense voltage at the selected power input node. |
