shouldn't pin 2 be higher than pin 1?

Q303 & Q503 or PNP's, not NPN's.
Q303/Q503=A1015
Q301=C1815
corrected

Well since you asked so nicely, I think to clear the faults, you use the remote pin.
According to data sheet.
But if whatever caused the fault condition still persist, then it will most likely return to the faulted state.
No fault remains.
I think that there is a typo about the capacitor used to reset.
How can the same size capacitor be used as in the no fault condition?

This is the part that I fail to understand, pg. 14:
"When the system has latched (either after overcurrent
or overvoltage condition), the system
needs to be reset via the Remote input. The C2
capacitor determines two different timings to the
Fault output :
C2=100nF => Trem1(ON to OFF)=8ms
C2=100nF => Trem2(OFF to ON)=24ms"
