 ADM1278 issue of input current

We test ADM1278, when ADM1278 turn the GATE pin already, and the MOSFET is closed

But we test the pin at the MOSFET input current we can see the yellow trace clamp to 392mV

 

We close the retry pin, there should not enable the retry function, if you can help clarify  what the current is 

 

Thanks a lot 

And after 20us then the current go back to zero

 

 

If you can tell us what is the passable issue ?

 

 

Thanks a lot
