Other Parts Discussed in Thread: SN65HVD234, ISO1050, ISOW7841, ISO7041

Hi,

My customer is looking for CAN trx 3.3V for e-mobility project.

speed max 1Mbps, no FD, Fault tolerant, the higher the better even though not primary concern. Application is cost sensitive.

Supply 3.3V.

I am looking for p2p CAN trx as below table

	Non isolated	Isolated version
Pinout	The same for the 2 versions	The same for the 2 versions
Alimentazione	3,3V	3,3V logic side and self supplied bus side

Do you have any recommendations?

Many Thanks,

Antonio

Antonio,

The highest fault protection we have for 3.3V CAN is +/-36V in our SN65HVD234/235/236 devices. These work up to 1Mbps, and are pin-to-pin compatible with all other 8-pin CAN transceivers with varying features on pins 5 and 8. Is this what you are looking for, or are you also looking for recommendations on isolated devices?

Regards,

Hi Eric,

Yes thanks, I am now looking for isolated devices that can be p2p with what you just suggested SN65HVD234/235/236 devices.

Do we have any?

Many Thanks,

Antonio

Antonio,

The closest released isolated CAN transceiver to pin to pin compatibility we have is the ISO1050, but that is still not fully p2p. And it is a 5V transceiver rather than a 3.3V. We don't currently have any 3.3V isolated CAN transceivers available, but there are isolated transceivers that support 3.3V IO.

Hi Eric,

Ok thanks I was indeed thinking of some iso trx like ISO77xx or ISO7041 or ISOW7841 to anticipate the non iso CAN trx 3.3V.

Many Thanks,

Antonio
