Hi @bullseyesolutions ,
The logo on the FA chip hints that it may be from Fuji Electric.
Could not find any datasheet though.
What is the product?
Cheers, heke
Thanks for the assistance. How do you guys find/look up the marking codes? I got this reading off the L9 component on the tester so I guess it is a diode.
Based on the part marking layout info in the respective datasheets for the three parts you mention, the BD46445G and the AP7365-15WG-7 don’t seem to be matches.
BD46445G marking:
AP7365-15WG-7 marking:
The 74LVC1G08GW,125 “AND gate” is a possibility, though the datasheet for that part only states that it is marked with “VE”, but not how it’s oriented on the part.
It looks like there’s a cap attached to pin 5 (Vcc) in your image, which would be typical for the 74LVC1G08. The other side of that cap should go to the ground plane. Pin 3 (GND) should go directly to the ground plane. Not sure how you could test if it’s bad, but pins 1 and 2 would be the two inputs, and pin 4 would be the output of the AND gate.
It could easily be some other part, too, but the 74LVC1G08 is a possibility.
Thanks for your input and after reading the datasheets again about the markings I agree its down to 74LVC1G08. These results were after sifting through the result list on https://smd.yooneed.one/ as the other results were not the same shape/style.
I didnt see VE listed in the datasheet and marking pattern is different then one on datasheet. There is no date marking on mines. I drew what the marking look like. Thanks for looking into it.
Oops. You are right. V-something codes hovering around the “VE” but no exact match. My bad.
The dotting concept hinted to Onsemi, but can easily be something else.
The most straightforward fix might be replacing the whole motherboard.
