    Thread Summary
    
                The user asked about the VDD1 power on/off threshold for the ADuM1410, specifically when VDD1 is 5V. The support engineer clarified that VDD1 is considered 'on' when within the 2.7V to 5.5V range and 'off' when set to 0V. For precise undervoltage lockout (UVLO) thresholds, the ADuM340E0 and ADuM340E1 are recommended.

    Hello.
    

    I'm using ADuM1410 and have a question for Pin#10:CTRL2.
    

    Accoring to data sheet, "Default Output Control. Controls the logic state the outputs assume when the input power is off. VOA, VOB, VOC, and VOD outputs are high when CTRL2 is high or disconnected and VDD1 is off. VOA, VOB, VOC, and VOD outputs are low when CTRL2 is low and VDD1 is off. When VDD1 power is on, this pin has no effect." What voltage is threshold of VDD1 power on/off in case VDD1 5V.

      Hi, 
      

      VDD1 being "on" would refer to being within the ADuM1410's valid supply range or 2.7V to 5.5V. "Off" would refer to VDD1 being set to 0V. 
      

      If a precisely defined UVLO+/- threshold is required, I would recommend the latest generation of standard data isolators which have an undervoltage lockout specification. Either ADuM340E0 for default low outputs or ADuM340E1 for default high outputs. 
      

      Regards,
      

      Jason
