Abstract :
A temperature-insensitive silicon carbide smart power switch connected in a high side configuration is proposed. Based on the temperature-insensitive comparator, the switch provides many important protection functions that include over-voltage detection, under-voltage detection, short load detection, and open load detection, all of which have stable operation over a wide temperature range. Once any of the above fault conditions is detected, the error status is fed back to shut off and protect the switch. Therefore, it is suitable to be used in harsh automotive and aircraft engine environments
