8681l Ic Datasheet //top\\ May 2026

Quick summary

The part number string "8681L" is ambiguous. Two main families appear in datasheet searches:

• OZ8681 / OZ8681L (also listed as 8681L / 8681LN) — battery/SMBus charge-controller ICs used on laptop/mainboard power subsystems (commonly found in repair parts catalogs; QFN packages).
• Z8681 / Z86C81 / Z8681 — Zilog/SGS microcontroller variants from the Z8/Z86 family (older microcontrollers, multiple derivatives and application notes).

Below is a structured guide to help you identify which device you mean, find datasheets, and use the IC correctly. 8681l ic datasheet

Q4: Where can I find a CAD model or footprint for the 8681L?

A: 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). Quick summary The part number string "8681L" is ambiguous

Final Verdict

The MAX8681L is a solid, simple step‑up for small to medium LED backlighting (e.g., 2–6 series LEDs at 20–200 mA). The datasheet is clear, with typical application schematics and efficiency plots. Watch for layout guidance and ensure your input capacitor is close to the IC. OZ8681 / OZ8681L (also listed as 8681L /
