Hi.
Can I use the Viso supply voltage output on the isolated side of a chip for powering the Vdd2 input on the same isolated side?
If yes, then why it's not mentioned in the datasheet? It would be more convinient for a design to connect it.
Or why it's not even connected internally if the chip's isolated side logic has to be powered to operate?
Does that chip need other separate power source and can't use it's own separated Viso source? And I have to use another separating DC/DC converter to power the Vdd2 input of ADUM6421ABRNZ3?
The Viso output is able to provide 60-100mA of current which is way more sufficient to power the Vdd2 input.
In the User guide (UG-1708, Rev.B file), there is the Vdd2 circuit, but connected to the P3 socket.
Why there is no any 0Ohm resistor or a jumper to select between external source or the Viso?
Does that mean that I have to provide separate power to that Vdd2 input of a chip?
