TCAN1042H: One input and two output CAN

Other Parts Discussed in Thread: TCAN1046-Q1

Dear Team,

Customer is looking for one channel input and two channel output CAN.

For 3.3V, 250k, SMD type and non-isolated.

Do we have suitable solution here?

    Hi Kuan,

    Currently we offer TCAN1046-Q1 as a dual channel CAN FD transceiver. It is a 5V, and non-isolated with independant supplies and mode control. If the customer is able to supply the 5V for this device, it would allow them to use a single IC to achieve the functionality of the image you shared. 

    If no 5V supply is possible, I would recommend using two separate 3V CAN transceivers.

    Note that both of these solutions would add two loads to the CAN bus so it may not be ideal for a large system. Instead, the customer may consider using some logic on the TX lines to consolidate the signal before it reaches the transceiver (TX_CAN = TX1 && TX2; RX1 = RX2). This would allow the use of a single 3V CAN transceiver and only present the bus with a transceiver single load per node. 

    Please let me know if you have any other questions.

    Regards,
    Eric
