What are these SOT23-5 components marked 7HUH and AAPQ?

Question

I am doing a reverse engineering project, but I can't find what these components are. Can someone identify them for me?

The components have the following text on them:

IC #1 = 7HUH

IC #2 = AAPQ

Here you can see the 7HUH and AAPQ + external components.

Can you show us a schematic of the reverse engineering you have done so far? Sometimes the external components will give you a clue as to the function of the IC so you can narrow it down — MCG, Commented Aug 15, 2018 at 13:40
Also, if you are reverse engineering the item you presumably have some idea what the device is for and what that part of the circuit is supposed to be doing. All this information would give useful clues. — Transistor, Commented Aug 15, 2018 at 13:41

I upvoted this question for doing it completely right. Close, clear shots of the components in question and one clear shot showing the board they are assembled on, with pointers. — Janka, Commented Aug 15, 2018 at 16:26

For the AAPQ I found:

MCP6001T-I/OT which is a SOT23-5 from Microchip and has a marking type "AANN" with NN lot/date code. MCP6001T-I/OT datasheet

For the 7HUH I found:

24AA64T-I/OT which is a SOT23-5 from Microchip and has a marking type "7HNN" with NN lot/date code.

(not great picture but couldn't find any other)
