To help refine this documentation for your project, please let me know: : The center of the QFN-16 package features

ΔT = P * θJA = 0.51 * 250 = 127.5°C

: Pins dedicated to overvoltage, overcurrent, and thermal cutoff paths protect the system from thermal runaway or hardware faults. Switching & Output

Sites like Wit Computers often list the IC alongside compatible battery models for Lenovo and IBM devices. We will also clarify the other possible interpretations

Ultra Librarian, SnapEDA, or the manufacturer's website often provide symbols and footprints. Alternatively, use the standard SOT-23-5 footprint from your EDA tool (e.g., KiCad, Altium, Eagle).

The chip gets extremely hot to the touch when the power adapter is linked. Troubleshooting and Repair Tips

✅ – Look for a second line or logo (manufacturer). ✅ Search the full marking – If the package is small, use "SMD code 8681L" on sites like Marking Codes or SMDParts.com . ✅ Consider alternatives – If this is for a regulator, comparator, or timer, common equivalents like LM393 , TLV1811 , or 78L05 may work. ✅ Use partial search – Try "8681" alone, but expect many false positives.

The (often listed as OZ8681L or OZ8681LN ) is a highly integrated, SMBus-programmable, multi-chemistry battery charge controller IC primarily used in portable computer systems like laptops. Technical Overview & Specifications
