Hi,
can I use the ESD Protection as per schematic on the ADuM4160? [It is to be on a peripheral]
PS- I do NOT want to use the PiC's VUSB in this case...
Thanks again!

Hello Yachaan,
I don't see any reason this implementation would be a problem.

Hello Yachaan,
After seeing the entire thing, I have a couple of comments.
1) the protection is to stop ESD and EOS from the cable being applied to the chip. Please review whether the ESD protection…
Hello Yachaan
On the upstream side, the ADuM4160 has an integrated pullup, and you would be doubling up. So definitely do not use an integrated pull-up on the upstream side.
I don't see that you need…
Here is my second application:
Under number4, alternatively.
Here only the Main controller runs on 3.3V, the rest on 5V.
It also controls the USB. You can see the the D+&D- IO's
What you don't see is the USB monitor & USB-DISC on the controller - it's lower down
I am still trying to find out how it works. I you have a suggestion, Please help.
My main Q is: is this correct to reference the ESD protection like I did?
[note that the input still depends on the firs Q's answer]
