8682l Datasheet Upd File

The 8682L (full part number OZ8682L or OZ8682LN) is a highly integrated SMBus Level 2 Battery Charger Controller manufactured by O2Micro. It is widely used in laptop power management systems, particularly in mid-range and legacy Apple MacBook Pro (e.g., A1286) and various notebook motherboards. Key Technical Review

The 8682L is a versatile component, suitable for various applications, including:

: It functions as a DC/DC converter and Switch-Mode Power Supply (SMPS) driver, which is essential for high-efficiency power conversion. Design Considerations 8682l Datasheet

| Pin Number | Pin Name | Function | | :--- | :--- | :--- | | Pin 1 | IN (Vcc) | Unregulated input voltage. Decouple with a 0.1µF to 1µF ceramic capacitor close to the pin. | | Pin 2 | GND | Common ground. Must be connected to the system ground plane. | | Pin 3 | OUT (Vout) | Regulated output voltage. Requires an output capacitor (typically 1µF to 10µF tantalum or ceramic) for stability. |

Practical design checklist (before you order)

  1. Confirm the exact part variant and temperature/package grade from the datasheet.
  2. Verify electrical characteristics at your operating frequency and temperature extremes.
  3. Budget margins: add 3–6 dB margin for noise/linearity and ±10–20% margin on supply/current.
  4. Check evaluation board or app note — copy layout, BOM, and matching networks if available.
  5. Plan thermal management: use thermal vias and follow recommended copper keepouts.
  6. Include ESD/protection if inputs/outputs connect externally.
  7. Prototype early and measure phase noise, return loss, and gain versus datasheet curves.
  8. If reliability/qualification is required, confirm screening options and lot traceability.

: Apply a thin, even layer of solder paste. Excessive paste on the center thermal pad can cause "pillowing," where the IC floats and the perimeter pins fail to make contact. AliExpress 5. Validation Checklist Verify the VDD voltage level is within the ±5% tolerance. The 8682L (full part number OZ8682L or OZ8682LN

The 8682L datasheet provides detailed technical specifications that are essential for designing and developing applications that utilize this IC. Some of the key technical specifications include:

When sourcing or replacing this component, it is vital to match the revision code found on the chip surface with the specific datasheet version to ensure full compatibility. Mismatched LN (Low Noise) variants may have different pin-to-pin characteristics or enhanced electrical protection that standard versions lack.
