I will use the ADuM3471 in a new design. Can I use the output VOD to monitoring
the voltage VISO? If there is a problem with the transformer then I have no
VISO (VDD2 unpowered), what is the state of VOD?

 

If VDD2 is 0V because VISO is 0V, then no pulses will be sent from side 2 to
VOD output of ADuM3471 and its watchdog will time out and VOD will  go to its
default output, which is 0V.
