TCAN1044V: Using the TCAN1044V as a CAN extender

Hi Jeffrey,

In order to use a standard transceiver like TCAN1044 as a bus extender, you will need to include arbitration logic on the digital signal lines between the transceivers. We have a reference design that I will link below that includes this logic. The reference design includes isolation between the two CAN buses, but this is not necessary if the goal is only to extend the bus.

Let me know if you have any questions on this design or the arbitration circuit.
