I have removed part of my original post ,here it is again:
Here is my view:
The 2 Mosfets are shown to be enhancement mode :
Q8- -N channel ,Q7- P channel.
Q7 is a "high side switch"
The voltage marked as " V_808 " will be present only after the voltage of the MP2307 output reached above Vth(thershold) of Q8.
In that case Q8 will be on.
In that time the Vgs voltage of Q7 will go lower than it's Vth and Q7 will be on as well.
The " V_808 " output will be a "step like" one, after power up/enable of the converter MP2307 .
That is different from the gradually rising(ramping) output of the converter.
The 2 diodes (D2,D3) in parallel suggest the output " V_808 " is relatively "high current",
so Q7 is probably a power Mosfet.
