For a 15A DC chopper I want some good fault protection. I already have a high side current shunt and sense amplifier for detecting slow overcurrent, but in the event of a hard short circuit this measure would be too slow (several microseconds) to save the FETs from destruction. I was hoping to find a FET driver with desaturation detection, similar to devices like this. However all devices with desat protection have very high trip thresholds (6-8V), which is suitable for IGBTs but not for FETs. Does anyone know of a MOSFET driver with such a feature?
