    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.

    Abstract: A method includes monitoring a load path voltage and an operating parameter of the transistor device; operating the transistor device in a normal mode when the operating parameter is below a threshold associated with the operating parameter, where operating the transistor device in the normal mode includes operating the transistor device in one of an on-state or an off-state based on a drive signal; and operating the transistor device in a fault mode upon detecting a fault based on comparing the operating parameter with the threshold. Operating the transistor device in the fault mode includes switching off the transistor device, operating the transistor device in the on-state includes adjusting the threshold in accordance with a first characteristic curve dependent on the load path voltage, and operating the transistor device in the off-state includes adjusting the threshold according to a second characteristic curve different from the first characteristic curve.
