Tested that circuit with one of my "new" ADM chips and saw NOTHING coming out of the CAN pins. I'm going to desolder the known good chip to test this circuit again but, given the difficulty of sourcing that chip, I've ordered high speed optocouplers to use with a regular CAN transceiver.
That ADM3052 isn't crazy special, it just has optocouplers built into it to be a single chip solution. It's pretty clear Sefs wanted as many pre-fabbed parts as possible, so I certainly don't fault the choice.
With the change away from the ADM3052, all of the components will be through-hole form factor, so it should be possible to set this up on a proto board like this one:
The shipment of components would have been here Thursday, but apparently UPS destroyed the package. I'll continue to keep you posted. That package also has a bistable solenoid to use with my EVCC to test CCS charging.
