Hi,
It is unfair to expect people to read e2e posts and figure out hardware bugs before designing a board. There is no mention in the datasheet that FUSE pin needs to be connected to VSS if not used. We left the pin unconnected. The FETs simply would not turn on. Finally I read this -
Soldering a QFN lead tested stretched my soldering skills! Please fix the datasheet ASAP.
