IC Marking Codes and Datasheets #2

[javieromex]

Looks pretty similar, however, SY8371B might be 3V (see attached only information I was able to find, only 11 pages).

See the first link - the webpage has the details you are requesting. For now, unable to download the full datasheet from their website but the landing page has the pinout.

Thanks, mon2, its present on Asus B1400CEPEY.

I found only SY8370 but it may be close. Which board uses the SY8371B?

Hello, looking for pinout of SY8371B Marking DFAXXX, DFA, DFADMB. Thanks!

Another one from monotlithic power, for AQPK marking the component is NB681AGD used in the HP SPECTRE X360 13 DA0X36MBAE0 Rev.E

hey everyone can anyone send me datasheet of this bluetooth ic?
this module and ic is on the harman kardon aura studio 3
i want make somewhere can buy this full module or single ic

[mon2]

Perhaps:

check the body and need to trace the cap pins

[mon2]

I believe the vendor is ONSEMI. Actually, looks more like NEXPERIA.

See here - similar style of markings:

Hello!

Im struggling a bit to identify this little 6 leg guy with the marking "-59-" or "_65_" not sure of the orientation...



It belongs to a Mac Pro 2019 logic board model 820-01136-12
No schematics or boardview available.

Can someone more experienced in this IC identification help?
Thank you

[mon2]

Thanks. To the OP - pour alcohol onto the top surface to clarify if the first marking is an '8' or a 'B'. Appears to be a 'B' to me. If 'B' then my guess stands. If '8' then agree with the correction - both are from ONSEMI.

Also confirm if the lower right leg is connected to anything else. If floating then 100% it is a zener diode.

ONSEMI part # MSB1218A--RT1G

I beg to differ!
That D2... reference suggests it's a diode. Also, that body proportions suggests a SOT-23, not a SOT-323. Also, leg 2 seems connected to nothing. It could be bridged to leg 3, but I don't think so. I don't even read BR, but 8R. So, my bet is MMBZ5241B, a 11V zener from Fairchild/ON semi. (1) Anode, (2) not connected, (3) Cathode.

[mon2]

To me, this appears to be from ONSEMI.
