    Hi
    

    I'm concidering ADGS1414D.
    

    Now I have a question.
    

    

    While the evaluation board is running, when I remove the controller board (EVAL-SDP-CB1Z), the switch settings return to the initial state of OFF.
    

    Is there a way to maintain the ADGS1414D switch settings even if I remove the controller board?
    

    Power is applied externally.
    

    

    Best regards,
    

    Yuya

      Hi Yuya,
      

      

      Thanks for considering the ADGS1414D.
      

      

      You are correct in thinking the switch will reset once unplugged.
      

      The SDP board is connected to RESET/VL pin through JP1. 
      

      Once the SDP board is removed, then the RESET/VL pin will no longer be powered and the ADGS1414D will return to its initial state.
      

      

      However, it is worth noting that the SDP board can be connected to the Evaluation board beyond initialisation and won't hinder the performance of the switch.
      

      

      Hope this helps!
      

      -Karen

        Hi, Karen
        

        Thank you for your reply.
        

        I understand that when the SDP board is removed, the RESET/VL pin is removed and the switch state is initialized.
        

        Best regards,
