How to choose the MOSFET for ADM1175-1

Hello,

what is the criteria for choosing the MOSFET switch to be used with the ADM1175-1?

From the data sheet on page 14, in a normal hot-swap event, the "FET Gate is charged up with a 12.5uA current source", then the "FET is controlled to keep the sense voltage at 100mV". From data sheet page 3, Vgate(max and min) depends on Vcc, which in my case will be changing overtime because it is a large 12.5 Volt battery.

I was thinking to use the Si1070X MOSFET from Vishay. How do I make sure that the Si1070X will work well with the  ADM1175-1 ?

 

Thank you,

 

Claudio
