SN65HVD230: SN65HVD230

Part Number: SN65HVD230

Tool/software:

Hello, I have to make a CAN interface with SN65HVD230.

Below, a minimum schematic.

Is it enough to achieve communication?

    Juan,

    For just functioning as a CAN transceiver, yes the schematic will work. The transceiver only needs power, the pull-down on Rs for Normal communication, and termination on the CAN bus to make sure the signals are properly conditioned.

    Please let us know if you have any issues.

    Regards,

    Hello Eric, thanks for answer.

    Which another function besides "CAN transeiver" can this chip achieve. Just to know if I am missing something.

    Juan,

    What I meant by that is this is the bare minimum for the device to function properly. In a typical CAN application, we also recommend a common-mode choke on both CAN lines and filter capacitors (10pF to 100pF range) on CANH and CANL separately for any high frequency filtering.

    We also typically recommend a protection TVS diode for any ESD or other voltage transients that may occur on the CAN bus. 

    So, the other recommendations are just for more filtered and reliable communication if the environment is noisy.

    Regards,

    Thanks Eric, after some research I will move to TCAN1042HVDR.

    Is the schema below fine?

    Juan,

    Everything looks good, note that if pin 8 is pulled down that means the device will not be able to go into Standby mode. Also, with pin 5 set to 3.3V, the logic levels for pin 8, pin 1, and pin 4 will all be translated to 3.3V.
