A colleague in New Jersey called me on the 1-800 this morning, asking for a favor. Could I upload a higher res photo of one of my Arcade1up Motherboards so he could read the chip? The one his customer brought in burnt up so he can’t read it.
He sent:
I shot him back a clear one
Here’s the chip ID:
- XA9220B
- WCYB1XC91XD
- Source
- Datasheet
- UPDATE: a caller emailed me with a few more useful datasheets. He told me his burn marks look exactly like mine in the picture & have to do with the temperature control circuit on the high voltage (~26VDC) segment of the IC. The chip is only specced for 26 celcius – awfully low for an unventilated unit
