Hi team,

Could you explain the pin connection for unused WAKE/ INH/ SPLIT pin for listed device? 

Customer used other device with p2p(which has no WAKE/ INH/ SPLIT pin), but has concerns of any EMI/ noise problem when implementing ours.

- TLIN1021-Q1

- TCAN1043-Q1

Thank you.

    Zena,

    Can you share the other devices which are p2p but with no WAKE/INH/SPLIT? If they are not using these pins still, the TLIN1029A-Q1 is a better device because it does not have INH or WAKE, but the same pinout.

    For the WAKE pin, it can be tied VSUP or GND if it is not being used. If INH is not being used, it can be left floating. SPLIT does not exist on our CAN transceivers, these pins are true no connect and so it doesn't matter what is connected to it.

    But again, can you share the competitor devices the customer was using so we can better match the replacements from our portfolio?

    Regards,

    Eric Hackett
