active miller clamp and desaturation detection in mosfet drivers?
(1) I don't see any difference between an Active Miller Clamp, and a decent low driver that can sink current when it's supposed to be driving low. However, specifying what it does suggests that they've thought carefully about keeping the gate voltage low in those circumstances.

(2) The desaturation function should be every bit as useful for a FET as for an IGBT. Under excessive current, it will turn the device off. However, the fact that a FET is ohmic while an IGBT looks like a BJT means that you might want to carefully review the threshhold voltage for the discrimination it will give you between normal, slightly excessive, and grossly excessive currents.
