PDF datasheet of 204 KB with a generic name that does not identify the component, manufacturer or part number. Opening it in any PDF reader will reveal which chip it covers. Datasheets give pinouts, absolute ratings, typical application circuits and electrical characteristics, which technicians use to check supply and enable pins, compare measured voltages with expected values and choose a replacement part. Confirm the marking on the actual IC matches the part number in the document before relying on it.
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 @ic_mosfet_pdf_datasheets. Enginerys does not host this file.
