Hi Sir,
We are found out the difference pin define between datasheet and ref design.
the pin31 TIDEP0058-somplc-fcc.pdf is show "DNC2", but datasheet sbos669a is show "PA_GND3".
the pin46 TIDEP0058-somplc-fcc.pdf is show "DNC4", but datasheet sbos669a is show "PA_VS3".
Could you please help to check Which one is correct?
