Texas Instruments document with the literature number SLUS786, revision H, provided as a 2.38 MB PDF. The file name gives the TI literature code rather than the part number. SLUS numbers are generally used for TI power-management datasheets, so open the first page to see which controller or regulator it covers. Once identified, such a datasheet helps you check pin functions, enable and power-good signals and typical application values while diagnosing a missing supply rail.
