ADuM7442S Digital Isolator UVLO Specifications

To Whom it May Concern,

 

I have a few questions about the ADuM7442S.

 

1. What are the under voltage lockout specifications for the ADuM7442S if any? I don’t think that there’s anything in the datasheet, just recommended operating conditions.

2. The ADuM7442S datasheet shows figure 2 as the “safety-limiting current” for the package as a thermal consideration.  I am wondering what kind of limits are on the current for a single input pin when the ESD diode is forward-biased.  I can’t imagine that at 50C it’s >250mA for a single pin, it can’t be limited by just the package heating. (If this question makes sense to you, then please feel free to answer.)

 

Thank you.
