Then this feature is unnecessary, because if the dc/dc is broken, then is no power in the mosfet driver, and I can not open the mosfet or the mosfet's can open by it self. I thik if any alarm UV Fault is present, then the battery contactor should be open.

I can move the transistor Q3 from the driver section to the battery contactor. On the opto. U9
