Datasheet //top\\: 8681l Ic

(full part number ) is a highly integrated SMBus programmable battery charge controller manufactured by O2Micro International Ltd

  • Supplier/repair catalogs list OZ8681 / OZ8681LN entries — search for "OZ8681 datasheet", "OZ8681L QFN datasheet", or part + "SMBus charger".
  • Read schematic/board trace to identify which pins correspond to SMBus, BAT, CHG FETs before replacement.

5. Common Confusion

  • Some “8681L” markings appear on different ICs (e.g., power management or motor drivers). Always verify the full manufacturer prefix (MAX8681L, LT8681, etc.).
  • If no Maxim logo, cross‑check with the marking code in the datasheet’s “Package Information” section.

3) Z8681 / Z86C81 / Z8681 (Zilog/SGS Z8 family) — microcontroller (practical notes)

  • Family: Z8/Z86 microcontroller family; variants include ROMless, masked ROM, different memory sizes.
  • Typical features: up to 24 I/O lines, UART, timers; up to 64K external addressable space on some variants.
  • Packages: DIP-40, PLCC, etc.
  • Use cases: legacy embedded controllers, instrumentation, application notes available for interfacing EEPROMs and peripherals.
