I have seen plenty of dead drives due to those mosfet drivers, some IR.8.1.2.. i can not recall, but i did not bother to check why or how, just left it to using cheap IRF540 or IRF740 output stages that have max 100V VGS and slapping 80V working voltage on the drives, so any coasting or hard brake would release the magic smoke.
I am sure you can figure out what company made those.
Fortunately i still have some in use as with 30-48V they are fine.
