I am using ADuM4135 for 3phase inverter circuit to drive IGBT module.
ADum4135 toggles fault pin low even if voltage at desat pin is not exceeding 9V.
The ADuM4135 does not register a fault in reaction to the Miller effect. It should only give a fault when the DESAT pin goes above the ~9V threshold. We have seen some spurious DESAT registration in systems near large RF sources. I'd like to follow up on this with a direct email. I'll contact you soon.
