Decoding IC combined batch+date code

[N_Cook]

Manufacturer's datasheet has no info on it but does carry a graphic showing
a representative label with this example as
N5BXXA
the ones I have in front of me have marking under the logo and device number
of batch+date code
N5H6PB
can anything be inferred from the use of XX in the graphic and hence meaning
of 6P ?

It may help if we knew what you know about the mystery component. ;-)

Who is the manufacturer? What is "the logo"? What is the "device
number"? Where can we download a "datasheet"?

What is "it"?

A photo may help. In fact it's often worth more than a 1000 bytes. ;-)
