TCAN1042H-Q1: What is the advantage of 70V BUS FAULT PROTECTION

Part Number: TCAN1042H-Q1

I see that 58V BUS voltage is sufficient in ISO 11898-2:2016(E) standard. What is the advantage of "TCAN1042HDRQ1" integrated with 70V BUS voltage?

    Hi Omer,

    As you can probably guess the 70V Bus fault protection is really only needed if your system where the CAN device is placed could see a 70V Bus fault. If your system couldn't possibly achieve this level of fault then it is probably overkill.

    We don't see a lot of customers using the 70V bus fault protection so in our newer CAN devices like the TCAN1044A (updated version of the TCAN1042) we only offer +/- 58V. If you don't need 70V bus fault protection then I recommend going with the TCAN1044A.

    Best,

    Chris
