    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

    IC #2 = AAPQ

    Probably Original Numbers Removed and In-House Numbers added.
    No Easy Way To Know what it really is.

    Not 'in-house' numbering but the usual non-informative SMD part numbering. There are SMD 'catalogs' available on line that can, in many instances, decode these numbers/letters to actual parts....

    Here's a typical catalog: http://www.sphere.bc.ca/download/smd-codebook.pdf

    although simply Googling "SMD part number xxxx" can often reveal the information you require.

    Manufacturers print anything on their parts so they can identify their production batches in-house. Next day, same part production may have a completely different markings.
    The correct part number appears only at the reel or bulk packaging labels.

    (As told by a manufacturer)

    Not 100%, however the AAPQ could be a MAX823REXK+T

    The marking shows 4 spaces and an AAP so the Q could be date/lot/Temp

    TI has a part again with a partial match 7HU. TL4050B25QDCKRQ1
    Again not 100% on this but might be something to look at.

    hi
    welcome to EP :)


    I will also go with Kellys_eye and Robert fay's recommendations, but be warned, finding SMD numbers can be difficult

    Robert has given you a great start, so once you have a possible normal part # corresponding to the SMD number
    then you can google a datasheet for that normal part number and see if the devices matches looks etc
    OFTEN, the datasheets will have the SMD part markings listed
