OK guys, I guess I be trying to use the High Side Smart Power SSRs. The only things I worry about right now it getting it to work because if I use the VN05Ns, that means I going to need at least 15 of these on a board, but if I use the VND05B which are the dual channels version, i only need about 8 of those. I not 100% sure how to understand the datasheet, but I was told in the past that the higher the RDS(on), the more power it needs to run. Since these relays will be drawing at least 3 amps each, but they are rated for more. Can anyone give me a idea what I should be doing. Are there any schematics that someone used these devices before?
