TCAN1145-Q1: Can it support selective wake-up during CAN-FD mode?

Part Number: TCAN1145-Q1

Hi team,

My customer is using TCAN1145 in OBC.

Q1: their customer has a requirement that Can TCAN1145 support selective wake-up during CAN-FD mode. 

Customer now can achieve selective wake-up under CAN mode and fail in CAN-FD mode.

Q2: Do we have p2p device can do selective wake-up under the CAN-FD mode?

    Hi Gary,

    1. Yes, TCAN1145 only supports selective wake with classic CAN, not CAN-FD. 

    2. Currently, we do not have a transceiver that supports SW with CAN-FD data rates. This is because arbitration typically is in classic CAN speeds to ensure maximum compatibility for all other transceivers on the bus. 

    Can you follow up via email so I can bring this request to our systems team?

    Best,

    Ethan
