Abstract
A gate drive circuit includes a first gate terminal, a second gate terminal, and a driver circuit including an input and including an output coupled to the first gate terminal. The driver circuit is configured to provide a drive signal to the first gate terminal to control a first switch to selectively couple a first current path to a first wire pair of a network port. The gate drive circuit further includes a switch including a first terminal coupled to the output of the driver circuit, a second terminal coupled to the second gate terminal, and a control terminal responsive to a switch control signal to selectively couple the output of the driver circuit to the second gate terminal to control a second switch to selectively couple a second current path to a second wire pair of the network port.
