Compact 116 KB PDF for the BQ24737 charge controller from Texas Instruments, filed under schematics. Since the name carries only the part number, the file is most likely the datasheet or an extract of it, so check how complete it is. Such documents give pinouts, a reference circuit and electrical limits that help technicians verify adapter detection, the ACOK signal, SMBus control and charge current sensing on laptop boards. Match the package marking on the IC before using pin numbers for measurements.
