    Hi,
    
 
    can I use the ESD Protection as per schematic on the ADuM4160?  [It is to be on a peripheral]
    
 
    PS- I do NOT want to use the PiC's   VUSB in this case...  
    
 
    
 
    Thanks again! 
    
 
    PS:The process to get to this result is shown below:

        Here is my second application:
        
 
        Under number4, alternatively.
        
 
        Here only the Main controller runs on 3.3V, the rest on 5V.
        
 
        It also controls the USB. You can see the the D+&D- IO's
        
 
        What you don't see is the USB monitor & USB-DISC on the controller - it's lower down
        
 
        I am still trying to find out how it works. I you have a suggestion, Please help.
        
 
        My main Q is: is this correct to reference the ESD protection like I did? 
        
 
        [note that the input still depends on the firs Q's answer]
