  • [SOLVED] (Find IC's Name) Unable to communicate between the computer and J-link Plus Compact

    Hi all, I currently have a J-link Plus Compact kit, but now when I connect to the computer, the COM port is not displayed, I checked, the components were damaged near the connection port like the red circle in the picture. Does anyone know what it is an IC with P/N? Please let me know to replace it

  • Hi,
    Before replacing anything, did you make sure that VCOM was not disabled for the J-Link Compact?

  • Hi,
    sorry for the delay in response.
    Even though it is probably not required anymore, please find the answer below:

    In general we recommend to make use of our trade-in program in such a case:
    segger.com/purchase/trade-in-program/

    The damaged part is an ESD-Protection.
    You could try to unsolder the part and check if the OB still works, as it also works without the part.
    If so, you can replace the part with a new IC (On Semi NUP4114UCW1T2G).
    If it does not, more parts were damaged by the over current and the whole J-Link is unusable.
