Abstract
Systems, circuits, and methods for detecting short circuit events during operation of an Insulated-Gate Bipolar Transistor (IGBT) from are provided. A short-circuit detection circuit is described is capable of creating an adaptive blanking time during which a short-circuit detector is blind to short-circuit events for the IGBT and after which the short-circuit detector is allowed to monitor and detect the short-circuit events for the IGBT.
