Just a shot in the dark ( IC identification help )
« on: July 11, 2024, 09:54:25 pm »
Hey guys I did something stupid I let the magic smoke out but anyway. It is a Chinese device but unfortunately I can’t read the rest of the marking so this is a shot in the dark to me and I wear trifocals it looks like a 555 timer I can see some markings but I was thinking maybe you guys may have run into one of these IC with similar markings. If not Advanced thanks anyway

I think we can be fairly sure its *NOT* a 555 timer.  However without seeing the rest of the board and having an idea of its application all we can do is guess from the remaining markings.

You need to reverse engineer a schematic or find someone else who has taken apart the same device and has a photo.

At least give some context about what it is. Showing a picture of IC with destroyed marking with no other info and not even a PCB picture is not helpful.

We definitely need a LOT more information, what is the device it is used in?, what is the identifier on the PCB, is it U5? (in case someone has diagrams for it).

Take photos from different angles to the light.
