Abstract
A control circuit and method are disclosed for controlling a current sense Insulated-Gate Bipolar Transistor (IGBT). In particular, the current sense IGBT creates voltage spikes in a sense voltage as a result of normal switching operations. The control circuit creates a blank period so that the voltage spikes are ignored and false detections of short-circuit events are avoided.
