ISO1050: CANH&CANL Protection circuit and component recommendation

Part Number: ISO1050
Other Parts Discussed in Thread: ISO1042

Hello,

Could you recommend ISO1050 TVS component for protection circuit and explain design consideration for this circuit?

Thanks!

  • Hi Paul,

    Thank you for posting to E2E! For CAN bus protection we recommend CPDT-12 by Comchip as an example diode to use with ISO1050 systems.

    This Application Report (SLLA419) details how to select CAN bus protection components for isolated CAN systems. We also recommend using ISO1042 over ISO1050 since it is a newer, more capable isolated CAN transceiver, as mentioned in the application report.

    Please let us know if you have additional questions.


    Respectfully,
    Manuel Chavez
