: Platforms like WitComputers or MacFactory provide specific compatibility lists for laptop models like the Lenovo IdeaPad 100S or Yoga 710. 8681L Datasheet, PDF - ALLDATASHEET.COM
No. The absolute maximum VDD is 10V, but the detection thresholds are fixed for a single Li-ion cell (3.6V-4.2V). For 2S packs, look for a dedicated 2S protection IC.
Proper PCB layout is critical to prevent switching noise from interfering with the feedback loop and to ensure proper thermal performance. Keep the path between CINcap C sub cap I cap N end-sub , the IN pin, and the GND pin as short as possible. Clear identification of all 16 pins (VCC, Ground,
A typical datasheet for the 8681L IC would include:
Sites like DatasheetSP , ALLDATASHEET , or DatasheetQ are excellent repositories for the 8681L.
The 8681L is engineered to manage the charging cycle of multi-chemistry batteries. Its most notable feature is : when a laptop is powered on, the IC monitors the current used by the system and allocates all remaining AC adapter power to the battery to ensure the shortest possible charging time. Technical Specifications Manufacturer O2Micro International Ltd. Package Type QFN-16 (Surface Mount) Communication SMBus Level 2 Operating Temp Application Laptop motherboards (e.g., Lenovo IdeaPad, Yoga 2 Pro) Key Features Keep searching
Designed for Lithium Polymer and multi-chemistry battery packs. Finding the Datasheet PDF
Replacement and Alternatives: Mention that the IC is available from various distributors.
What is the 8681L IC? Explain that it's a highly integrated SMBus programmable multi-chemistry battery charge controller.
Main power supply input pin. Must be decoupled with a high-quality ceramic capacitor to ground.
Supports adjustable output voltages starting from 0.6V or 0.8V up to a high percentage of the input voltage.
