Other Parts Discussed in Thread: TCAN1042HG, TCAN337,
Hi,
Good Day. I have a customer who is working with ISOW7841. Please see below his query for your reference. Thank you very much.
For a CAN application using TCAN1042HG we do need a 5 V Power Supply on the isolated side.
Primary Side of ISOW7841 is supplied with 3.3V.
PCB is ready - system is working.
Now we discovered a tiny little line in the manual that this operation mode "is not recommended".
Question: Our system so far works fine with the "not recommended" settings. What problems will we have to face ?
For a re-design we consider the TCAN337, but this device is not as protected on the CAN bus-side as the TCAN1042HG.
Please explain the situation and potential issues coming up under which conditions ( i.e. temperature, current drawn )
Section 9.4 Device Functional Modes of ISOW7841 is the one that customer is talking about not recommended.
Best Regards,
Ray Vincent
