TCAN1042G-Q1: 12 V OUTPUT CONTROLLED AREA NETWORK TRANSCEIVER

DEEPAK VERMA68
Intellectual 410 points
Part Number: TCAN1042G-Q1

I have seen in  most cases that the CANH  and the CANL signal are bound between 1.5 and 3.5 . so do we have  a product in ti of automotive grade that have 12 v output.

    Deepak,

    The CAN bus recessive level is nominally 2.5V for a 5V transceiver, this is part of the CAN standard. For the 12V output, are you saying 12V output on the communication bus?

    Deepak,

    The common mode range on the TCAN1042 family ranges from -30V to 30V. If your CANH and CANL signals are centered around 12V, this will still work, as shown on page 13 in the datasheet:

    This doesn't show the 12V exactly, but shows that the receiver driver can work beyond 12V.

    What are the other requirements for this application? You could also look into the LIN communication protocol. It is single-ended but references the car bettery voltage for the high output on the communication bus (0V - 12V). Let me know if CAN is necessary, or if the 12V output is the only requirement.

    Regards,
