    I am using ADUM5402 in our design what should be done for unconnected input and output pins

  • About the "Load Regulation" characteristics of ADuM5402


    I want to use ADuM5402.
    I have a question, please let me told.

    The D/S has the following description of "Load Regulation".

    I want to know how an error of 1 to 5% occurs at 10mA to 90mA.

    In the Load Regulation of ADuM5402,
    Can you give me…

  • ADuM5402 About Current consumption


    We are evaluating the ADuM5402.
    Please let me ask you a question because it behaved outside the specifications during the experiment.

    1. The current consumption of ADuM5402 is recognized as ~ 100mA as shown below.
    However, in the experiment, a current…

  • ADuM5402 question

    I would like to know if it is OK to change the Viso pin 16 while the chip is
    powered (changing from 3.3 V to 5 V secondary voltage, controlled from the
    primary side using one of the internal channels). It would help powering /
  • ADuM5402 input behavior

    We use the ADUM5402 on many of boards to generate the isolated 3V3 for our POE

    As part of that circuit a 3V3 voltage is generated through a FET into Pin 12 of
    ADUM5402 to indicate when POE power is applied. The voltage comes…
  • ADuM5402: EMI layout recommendation

    Could you please kindly recommend the type of ceramic disc safety capacitor to
    mitigate EMI? There are various type of ceramic disc safety capacitor, for
    e.g., X1, X2, Y1, Y2.
    I would appreciate if you could recommend a general one which…
