I use the ADUM5411 for isolate 3.3V and 5V logic.
so I designed circuit as following :
I konw that the VDD1 is a voltage Input pin, but VDD1 is measured 4V.
3V3_MAIN is my board's main power, but it's voltage go up to 4V cause VDD1.
I know that VDD! is indpendent of VDDP as datasheet :
I don't know what's the problem??
I want to know if tthere is a any problem on my curcuit?
