Datasheet for the Texas Instruments bq24741, a battery charge controller used in notebook power circuits, supplied as a 1.37 MB PDF. Charger chips like this handle adapter detection, input current limit and charging of multi-cell packs, so the datasheet is useful when a laptop does not charge, will not run from the adapter or has a shorted input rail. It gives the pinout, typical application circuit and pin voltages for comparing against measurements. Check the exact part marking on the chip before relying on the pin assignments.
