Abstract:
A power circuit is described that includes a switch coupled to a resistive-inductive-capacitive load and a driver coupled to the switch. The driver is configured to detect an emergency event within the power circuit. After detecting the emergency event within the power circuit, the driver is further configured to perform a controlled emergency switch-off operation of the switch to minimize the maximum temperature of the switch during the detected emergency event and switch-off operation.
