QCan You use the Vdd1 and Vdd2 to supply other circuits on the board and how
current is available ?
AWe do not support that mode of operation. The Vddx supplies are not intended
and do not have
the capacity to supply power to other external circuits outside of allowing for
capacitors and providing bias for the external pull-ups.
The datasheet states that: If 5 V is supplied to VBUSx, an internal regulator
creates 3.3 V to power the xD+ and xD− drivers. VDDx provides external access
to the 3.3 V supply to allow external bypass as well as bias for external
