Small 94.3 KB PDF for the BQ24728 battery charge controller by Texas Instruments, placed in the schematic category. With only the part number in the name, it is likely a datasheet or a short excerpt, so check which sections are present. The information is used to identify pins, follow the typical charger application circuit and check adapter detect, current sense and MOSFET gate signals on a laptop that does not charge. Confirm the IC marking code matches this part before relying on pinouts during measurement.
