Renesas datasheet for the ISL6251A, dated 2004-11-03 and supplied as a 1.05 MB PDF. The ISL6251A is a battery charger controller often found in older laptops, regulating adapter current and charging current. The document gives the pinout, the function of each pin, typical application circuits and the electrical limits. Technicians use it to check expected voltages on the charger IC, trace the adapter detection and battery charging path, and confirm part substitutions. Compare the package marking on the board before relying on any pin numbers.
