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!
PS:The process to get to this result is shown below:
ADuM4160

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…
3] almost forgot about the incoming signals from limit switches.
Also through an ADuM.
Corrected:
"The ADuM3440 is probably not the best part for limit switch application. This part is our highest speed coupler, and we eliminated the glitch filter in favor of high throughput. A lower cost solution would be the ADuM3400A which is slower, and has a glitch filter. One is a drop in replacement for the other."
