Tool/software:
We have a set of boards with this chip one one has the markings 2KV which I think is correct but doesn't work. However we have an earlier build which we believe is the same chip and this has marking SIG, and that works perfectly,
Slightly confused , can you identify what the chip marked SIG (or S1G) as we have 500 boards out there working with SIG, but not with the later 2KV ( which seems according to datasheet be the correct part)
