Manages power sequencing, keyboard/touchpad matrix scanning, battery charging, and thermal monitoring.
You can find various iterations of technical documents on ALLDATASHEET or IC-Components , though these are often "short-form" versions. For a full "patched" datasheet or specific pinout maps, it is recommended to search laptop-specific repair forums (like BadCaps or VinaFix) where boardview files provide the most accurate real-world implementation.
