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.

DrMOS,Power IC`s,EZBuck DC-DC Regulators.

Some IC datasheets can have a different part number called a Global Part Number , for example
SY21249FTMC ,Global part # for SY8370FTMC
----------------------------------------------------------------------------------------------------------------------------

Top markings

The first 2 or 3 characters are the marking code,the next 3 are Year, Week and Lot number.

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.

Top markings

Markings are:

AABYM     AA YM
DNN       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.
