ADM3056EBRIZ - Isolated Power for VDD2


Do we need to give isolated power for VVD2 of ADM3056EBRIZ to achiveve the CAN Bus isolation?

Please suggest any Isolated power supply convertors.

    Hi Selvaraj, 

    If there is not power available on the bus side, then an isolated power supply from the logic side will need to be provided. 

    The ADM3055E and ADM3057E have an integrated isolated dc/dc converter to supply the CAN FD transceiver. When there is additional circuitry on the bus side that requires power, the LTM2889 may be a good fit.
