Abstract
An embodiment method includes detecting an inverse current condition at a switch, and driving a node associated with a switch driver driving the switch to a predetermined voltage in response to the detection of an inverse current condition at the switch. An embodiment switch device includes a switch driver configured to be coupled to a control terminal of a switch, an inverse current detector configured to detect an inverse current condition at the first and second load terminals of the switch, and a voltage driver configured to drive a node associated with the switch driver to a predetermined voltage in response to the inverse current detector detecting an inverse current condition.
