Abstract
Systems, circuits, and chips for protecting transistors and circuits containing transistors are provided. As an example, a transistor (e.g., an Insulated-Gate Bipolar Transistor (IGBT)) monitoring system is disclosed to include an IGBT desaturation detection circuit that is configured to check and monitor desaturation functionality of the IGBT before startup of the IGBT as well as during operation of the IGBT.
