  • 820-00840-A blown mosfet

    Hi,

    I have an 820-00840-A that had a liquid spill. Q7900 is blown, it is a TI CSD58889Q3D according to the schematic. I can't even find a datasheet for that part#, does anyone know where I can source some of these or something equivalent. A datasheet would be nice. Pins 1 and 2 are shorted to pins 6, 7 and 8. Does this sound like it probably killed the PCH?

    Just finished writing a feature in FlexBV that does just this sort of thing. Here's a snap shot of other boards that have that part, maybe you have one as a donor.

      Hi Paul,

      That is a killer feature, thanks for letting me know. Unfortunately, I don't have any of those as donors but I have an 820-00840 donor on its way from China so I may just have to wait until that arrives before I can start troubleshooting this job.
