Hi Faicel,

I am not sure what signal you are referring to; the NUP' device appears to be protection diodes only. These should clamp in an over-voltage situation and return to normal when the voltage returns to the regular operating range. I think this should happen passively without the F28027 having to intervene?

Thank you for your answer
the NUP don't returns to regular operating range, it is still bring out a signal
