8681l Ic Datasheet |link| 💫

: Due to its surface-mount design and critical role in power delivery, replacement should be performed by qualified personnel using specialized soldering tools.

: Level 2 SMBus programmability allows for precise communication between the battery, the IC, and the host system.

: When the system is powered on, the IC dynamically allocates all remaining AC adapter current—not currently in use by the system—to the charger. This ensures the shortest possible charging time. 8681l ic datasheet

: Found specifically in Lenovo IdeaPad models such as the U460 and U460s.

: Typically comes in a QFN-16 (Quad Flat No-lead) surface-mount package, though some variants may refer to a 40-pin configuration depending on the specific board integration. : Due to its surface-mount design and critical

: Includes safeguards against incorrect voltage, short circuits, and internal overheating to protect both the battery cells and the motherboard. Core Functional Features

The 8681L IC is designed for efficiency and safety in portable electronics: This ensures the shortest possible charging time
