Datasheet for the BQ24753A, a Texas Instruments battery charger controller used in notebooks, provided as a 2.06 MB PDF in the schematic section. Expect pin assignments, a typical application schematic, timing and voltage specifications and package drawings. On the bench it helps when diagnosing no-charge faults, checking adapter detection, current sense resistor voltages and gate drive to the power MOSFETs. Make sure the chip on your board is the A version, as suffix variants may differ in behaviour or pinout details.
