Part Number: TCAN844-Q1

Hi team,

This is Yuxin in TI SEM team working on 2W ABS reference design, and now using TCAN844-Q1 as the CAN transceiver. Could you please help to review this SCH design? Any recommendations on the placement of some key components? (such as any CAPs be closed to the device). Thank you!

    Hi Yuxin,

    Looks good overall. Yes, all supply caps should be as close as possible to the IC pin (may also include cap place holders on the bus), CMC closer to the IC pin then the termination, followed by ESD as close as possible to the connector similar to the data sheet's layout example, thanks.

    Best Regards,

    Michael.
