Hi community I am working with gate driver vnd7020.

I have already implemented the reading of the current (I) for both 2 oyputs and temperature for every chip

Now i want to implement the self diagnostic from the driver.

I want to detect the overload and undervoltage condition. 

What is nopt clear is what i have to expect to have from the adc reading in both the conditions ()

if i understand correctly if i read the adc in the same case as i am reading the current if i find VsenseH that means that has been the overload condintion? 

So this means that when i read the adc value from the mcu i should expect 0 or 4096 (max range for my adc)??

Another question is about how to simulate this condition in the gate driver without doing an overload.. 

Thanks a lot for the answer
