Hi,

While repairing a turn coordinator indicator, it’s gyro motor wasn’t spinning, when powered only the red flag would disappear and figured later the following IC FUA78MG wasn’t working( goes to gyro motor and does not produce output to run gyro motor). Does anyone have any data sheets or info about this IC?

Thanks

 

Is this the IC that you're using? https://www.digchip.com/datasheets/parts/datasheet/161/UA78MG-pdf.php

Yeah, I think this should be fine. Only the F in the one I have is missing. But I guess both are the same or similar.
