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.

Short-circuit detection circuits, system, and method

Systems, circuits, and methods for operating an Insulated-Gate Bipolar Transistor (IGBT) are provided. A switching circuit is described that includes a first current path and a second current path. The first current path carries current away from the gate of the IGBT during a first phase of switching and the second current path carries current away from the gate of the IGBT during a second phase of switching.
