One of the biggest challenges for a technician is finding a suitable replacement.

Precision programmable constant-current (CC) and constant-voltage (CV) charging profiles.

Input Sequence: 3ms High, 7ms Low, 2ms High... 8682l ic datasheet

Synchronous clock input line driven by the laptop's Embedded Controller (EC) or Super I/O chip.

Some revisions of the 8682L indicate thermal regulation with LED slow blinking; others simply lower current. Verify with your batch.

The 8682L IC operates via a 16-pin QFN configuration. Understanding the pinout is critical for troubleshooting and board-level repairs. While exact pin functions can vary slightly based on the board manufacturer’s implementation, the QFN-16 OZ8682 generally includes the following types of pins: Power input for the IC itself. BAT/BATT: Battery voltage sense input. ACIN/ACOK: AC adapter detection and status signals. It wasn't a proper PDF

If you cannot find "8682L," search for:

, allowing the system to draw power from both the battery and the adapter simultaneously to handle peak loads. Package Type

The 8682L is a high-performance, programmable constant current LED driver controller typically found in modern lighting systems and backlight units. Because it is a specialized component, understanding its pinout and electrical characteristics is vital for repair or circuit design. 8682L IC Overview One of the biggest challenges for a technician

You will typically find the 8682L / BA682 in:

Understanding the is crucial for circuit board diagnostics, trace repair, or validating voltage injection rails. The 16 pins are distributed evenly across the four sides of the silicon casing, heavily optimizing the power-ground paths. Primary Label Name Technical Description & System Function Power Inputs DCIN / VCC

| Question | Answer | | :--- | :--- | | | Unknown, likely NOT. A user on RepairLap asked this exact question, but no definitive answer was provided due to a lack of datasheets for comparison. The OZ8681 features simplified SMBus control and is available in the smallest package on the market. Given the differences, they are not recommended as direct substitutes without a schematic. | | Is there a known equivalent replacement? | Potentially the UP1589Q. An online reference suggests the "8682l datasheet rt8239b equivalent up1589q replacement". This is unconfirmed. The best practice is to replace it with an identical OZ8682LN-C1-0-TR . | | Where can I find a schematic using this IC? | Full schematics are elusive. However, schematics for laptop boards known to use this IC (e.g., Lenovo NM-A681, Quanta JW2) may be found on repair forums or schematic repositories. A forum user posted a link to a schematic (filename Quanta_JW2_UMA_Intel_Chief_River_Rev1A.pdf ) which likely contains the 8682L, but the link was no longer active. |
