    Top markings

    Markings are:
    Code:
    AABYM
     DNN
    With the first 2 or 3 characters being the marking code.AA are letters or digits,B is generally an = – or ' ' .YMDNN is the datecode/batch number.

    The package also matters, different ICs with different packages can have the same marking code.

      Datasheets & Other Info

      Package information,including Top Marking per package type and letter suffix - https://www.monolithicpower.com/en/s...formation.html

      Top format Marking Decoding - https://cdn.badcaps-static.com/pdfs/...3299cc5945.pdf
      -------------------------------------------------------------------------------------------------------------------------------------

      Top markings

      Often with an horizontal line above the markings, markings are:
      ____
      XXXY
      LLL
      ___
      XXY
      LL

      MPYW
      XXXX
      LLL

      with XXXX , XXX or XX the marking code specific to each IC model, Y a year code, W a week code and LL or LLL a batch number.

      For smaller packages, often with a vertical bar on the left (matching with pin 1).
      NOTE: Some TI parts also have the vertical bar on the left,but will often have dots or dashes above or below the marking code
      Code:
      |XXXY
      with XXX the marking code and Y a year code.

              IC Marking Codes and Datasheets

              onsemi & Fairchild
              ----------------------------------------------------------------------------------------------------------------------.
              Datasheets & Other Info

              Fairchild is a part of onsemi since 2017 . Some onsemi parts will have the Fairchild logo

              onsemi was previously named ON Semiconductor. Datasheets https://www.onsemi.com/products
              ----------------------------------------------------------------------------------------------------------------------.

              Top markings

              Some smaller IC`s have the same marking code for different packages,or the same packages with
              the same footprint but in a different case size.To differentiate between the case sizes or a Voltage
              option the marking can be rotated 0,90,180 or 270 degrees from the pin #1 reference.

                      Datasheets & Other Info

                      There are no datasheets available at the website http://www.o2micro.com/

                      There are some Application Diagrams included in the o2 product catalogs,but too blurred to be of much use.

                              Top markings

                              Larger packages have the AO logo,an A inside a circle.Part numbers for larger packages are on the first line
                              with Year,Week and Lot codes on the second line below.
                              Parts with 4 letters/digits code on the top line have either 4 letters or 2 or 3 letters followed by digits.The
                              last 2 digits can be a special parameter code and option.
                              The package also matters, different ICs with different packages can have the same marking code.
