We built a prototype board with this part, using the reference design information in the data sheets, etc. It worked. Now we have a production run of boards, and they are not starting / running.
Went through, checked the resistors, they measure as per the schematic. The FET isn't blown.
We have the same result if powered by POE, or the local adapter input. So far, everything looks like it is as it should be, but no activity.
Any ideas what to look for?
