TCAN1145-Q1: Placement suggestion

Part Number: TCAN1145-Q1

Hi Team,

A customer have a TCAN1145DMTRQ1, the traces of which are routed to the microcontroller through little long traces which are also exposed to high di/dt in some portion. In this case would you please suggest us a suitable position for the CAN IC, or some technique so that it is not susceptible to the noises.? Please see image below:

Thanks in advance.

Regards,

Marvin

    Marvin,

    Routing the CANH and CANL signals around the high di/dt area is suitable as long as the traces are matched in length and routed differentially. Is it possible to share a more detailed image of the possible layout to understand any changes that can be made?

    Regards,
