TCAN4550: CAN controller + CAN Transceiver solution with isolation

JH Shin

Part Number: TCAN4550

Tool/software:

Hello.

My customer is looking for a CAN controller + CAN Transceiver solution with isolation.

Is there a solution that can be connected in isolation when configuring a CAN controller + CAN Transceiver outside of an MCU or processor?

Thank you.

    Hello JH,

    The recommended solution is to use the TCAN4550-Q1 with an Isolated CAN transceiver.  This bypasses the internal non-isolated CAN transceiver and brings out the TXD and RXD signals from the Controller to the GPIO1 and GPO2 pins so that they can be connected to the external isolated CAN transceiver.  You can find TI's Isolated CAN Transceiver portfolio at this (Link).

    Regards,

    Hello Jonathan,

    Thanks for your reply.

    The settings you provided are described as one of the test modes for debugging the TCAN4550-Q1 device. Is it okay for a customer to use the TCAN4550-Q1 in this mode with an isolated CAN transceiver in a commercial system?

    Regards,

    JH

    Hello JH,

    Yes it can be used in a commercial system.  It is only called "Test Mode" because the various Compliance Standards tests are defined separately for the Controller and Transceiver which requires the internal TXD and RXD signals to be directly accessed.  Because it is assumed that most customers will use both the controller and transceiver as an integrated device, the "Test Mode" would only be required for compliance testing.  However, this does not prevent the device from being used in either a standalone Controller or Transceiver.
