    Hi Iven,

    What is the application?

    Please see comments below:

    1) What is the PVDD voltage?
    2) Please check VCC2 connections on U102 and U103. D+12V violates absolute maximum voltage of the device.
    3) It appears ISO7242C is the correct device for U103. Please confirm.
    4) R104 should be 1Ohm, not 1kOhm.

    Please make sure the GVDD/VDD supply meets the requirements of section 8.2.1.2.2 Current Requirement of 12-V Power Supply
