I am doing a reverse engineer project but I can't find what these components are. Can someone help me?

The components have the folowing text on it:

IC #1 = 7HUH 7HUH7HUH

IC #2 = AAPQ AAPQAAPQ

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

    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 Aug 15 '18 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 Aug 15 '18 at 13:41
  • IC1 could be TI TL4050B25QDCKRQ1. IC2 could be MAXIM MAX6826. – winny Aug 15 '18 at 13:50

    @winny post that as an answer – Voltage Spike Aug 15 '18 at 15:46
  • Thanks for your help But I have tried it this way ( https://electronics.stackexchange.com/questions/334128/how-do-i-identify-smd-components-or-how-do-i-identify-any-component/334129#334129 ) – Dennis de Graaf Aug 15 '18 at 15:49

    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 Aug 15 '18 at 16:26
  • I doubt the TL4050B25Q because it only uses two of the five leads. In that ciurcuit, all leads are connected. I also doubt the MAX6826 because it has 6 leads. – Janka Aug 15 '18 at 16:38
  • @Janka Thank you for your respond. But the pins 2,4 and 5 from the TL4050B25Q are not connected in the datasheet and are connected in the PCB. – Dennis de Graaf Aug 15 '18 at 16:50
  • Yes, exactly. That's why I doubt winny's answer in the comment is correct. – Janka Aug 15 '18 at 17:01
  • These are definitely not the "tiny logic" chips. The tiny logic has GND on pin3 and VCC on pin5; the left IC has GND on Pin4, and the right one has it in reverse. I think the left one could be a voltage-reset supervisor. – Ale..chenski Aug 15 '18 at 17:34
