dual useage of gate output on ADM6820

I had a question about a way to use the ADM6820 gate output for a active high enable power device (like a DC/DC converter) as well as for the intended N mosfet gate. This is so I can use the same device for all my needs. So it wasn't clear to me if when the gate output is still tied to ground after the UVLOW is cleared.  Also the data sheet does not state how much current the gate output can sink when it is driving to ground. Would it be enouph to drive a pullup resistor in the low state in the mA range?  I attached a rouph circuit for what I was thinking about.

 

Thanks
