Texas Instruments BQ24765 charge controller datasheet, 1.54 MB PDF, listed in the schematic category. The name gives only the part number, and the document typically contains pin descriptions, the reference application circuit, electrical characteristics and package details. Repair technicians use it to check the adapter detect and current-sense pins, verify switching MOSFET drive and understand why a laptop fails to charge or switch between battery and adapter. Confirm the IC marking on the board matches this part before relying on pin numbers.
