I searched the forum for similar threads and didn't find the right answer.
Why should I use galvanic isolation in a system that contains only one power supply (a battery)?
I don't have the right argument to convince my co-worker that using isolators (for e.g. the ADM3057EBRWZ-RL) in a system with only one battery is pointless.
Simplified block diagram of the system which I described earlier:
This is the way the system looks and it can't be changed. The question is: Do you see any reason to put an ISOLATED CAN transceiver here?
And to avoid further questions:
- Environment is not noisy.
- wires between PCBs, battery etc. are short (1 meter max).
- This is not CAN FD, data rate is very low.
