I tried to find that AA9 552 light sensor ic mentioned and found a datasheet of this smd ic with also 6 pins =>
https://www.s-manuals.com/pdf/datasheet/m/a/max4599_maxim.pdf
And looking with that smd code on the Aliexpress website they say it is this ic => NCP5359AMNR2G (Marking AAV AAL AAK AA4 AA9 AA*) DFN-8 Gate driver chip, which however has 8 pins. So I guess you already checked those.
