We are using 4 off ADUM4135 in a power converter full bridge circuit, and are seeing occasional FAULT signals, even though the DESAT pin is tied to GND2.
We have VDD2 at 20V and VSS2 at -4V to drive SIC MOSFETs.
Adding more decoupling right at the VDD2 pins didn't help, so we suspect some sort of radiated noise issue.
To minimize some of the effects, we are considering linking the /FAULT and /RESET pins - any comments/ issues with that?
Any support much appreciated.
