It's an MAX9019EKA Dual, Precision, 1.8V Comparator from Maxim Integrated.

From the datasheet, we have markings info confirming the top mark as AEIU:

This was found by searching SOT23-8 AEIU. First result in google images was from Aliexpress, showing a chip with the exact same markings (the same font/layout) with the seller listing the part number:
