This is my first time posting here. I want my device to pass the Low voltage directive testing and that includes ESD stuff.
So as you can see below, my device is Li-ion charger with isolated PSU.
The question: Where should I put the ESD diodes(like ESD9B3.3ST5g or PGB01 series)? At the moment I think they should be connected as in the image. Data or power supply pins - TVS - mains ground.
I have read several topics regarding connection of grounds and it seems kinda messy, everyone has their own opinion and I can't really decide what is the best solution.
