PDF documentation for the Texas Instruments BQ24735 notebook battery charger controller, 1.48 MB, catalogued as a schematic. The name states nothing beyond the part number, so treat it as a datasheet covering pins, typical application and specifications. Technicians consult it when a laptop will not charge or power from the adapter, checking voltages on sense, gate drive and enable pins and confirming the surrounding resistor and capacitor values. Verify the marking on the chip matches before taking pin positions as given.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopbios21. Enginerys does not host this file.
