When the laptop is powered on, the IC dynamically allocates all remaining AC adapter current—not currently in use by the system—to the charger to ensure the fastest possible charging time. Specifically the IdeaPad 100S-14IBR , Yoga 2 Pro

The 8681L operates as a conforming to standard Smart Battery System (SBS) protocols. Its primary responsibility is to dynamically balance energy between the incoming AC adapter wall power, the system load (the motherboard components), and the internal battery pack.

While specific parametric behavior should always be cross-referenced with official vendor documents like Alldatasheet , the general operational tolerances for power management components of this class include: Standard Value Range QFN-16 / QFN-24 Communication Protocol SMBus (System Management Bus) Supported Chemistries Li-Ion, Li-Polymer, Multi-Chemistry Battery Type Operating Junction Temp ( TJcap T sub cap J ) -40 to +150 Storage Temperature ( Tstgcap T sub s t g end-sub ) -55 to +150 Pin Configuration and Architecture

Bootstrap pin. Requires a capacitor to SW to drive the high-side gate. IN
