Abstract
Electrical circuits and methods for protecting a semiconductor switch in response to detecting a short-circuit condition of the semiconductor switch are presented. An electrical circuit includes a latch-reset portion that disables or enables the semiconductor switch by connecting or disconnecting, respectively, a gate of the semiconductor switch to a source of the semiconductor switch. The circuit also includes a power source portion that is energized by a voltage pulse that drives the gate of the semiconductor switch. The power source portion provides voltage and current to other parts of the circuit so that no external voltage source is needed to operate the circuit. The semiconductor switch may be a silicon carbide MOSFET, which may have a threshold voltage that changes with temperature and age. The circuit can account for such changes.
