If you are searching for this IC datasheet, it is likely for board-level repair:
: You can find replacement chips from electronic component retailers like Nexsys Techno or Motherboard.lk . Common Identification Marking Marking on Chip : Usually labeled as 8682L or OZ8682LN .
The 8682L plays a critical role in system architecture by safely throttling power between the external AC adapter, the system load, and the Lithium-Ion (Li-ion) or Lithium-Polymer (Li-Po) battery pack. Its defining feature is the technology. This feature allows the battery to dynamically assist the AC adapter during brief periods of peak system load, preventing the laptop or device from shutting down due to adapter overcurrent limits.

: Like most O2Micro controllers, it likely includes internal thermal shutdown (TSD) and over-voltage protection to prevent board damage during faults. Typical Repair Context
1 – VIN, 2 – GND, 3 – VOUT (fixed voltage). No enable pin. 8682l ic datasheet
: Manages power consumption while delivering peak performance, handling complex multi-tasking scenarios like signal processing and communication protocols simultaneously. Applications and Use Cases
:
Features logic for motor control (in industrial applications) and safety interlocks with precision.
Based on cross-referencing with common part numbering schemes from Chinese semiconductor houses (e.g., FM, TC, or HP branding), the 8682L often features: If you are searching for this IC datasheet,
Current sense input (Positive/Negative) for the battery charge current. VFB/FB: Voltage feedback from the battery. DRV/Gate: Drive signal for the external MOSFETs. COMP: Compensation pin for the internal error amplifier. ICTL: Charge current control. 4. Typical Applications
: Often found on Apple MacBook Pro and other major brand laptop motherboards as the primary charging controller.
Ensure the external MOSFET isn't shorted and the VCC capacitor is healthy.
The 8682L is an integrated circuit (IC) designed for specific applications, likely within the realm of electronics or telecommunications. However, without a direct datasheet provided or a widely recognized part number like "8682L," it's challenging to offer a detailed, accurate review. Integrated circuits with such designations are often specific to certain manufacturers or are used in niche applications. Its defining feature is the technology
The (also identified as OZ8682L or OZ8682LN ) is a high-performance battery charging controller integrated circuit primarily used in laptop power management systems. Manufactured by O2Micro International , it is designed to manage and regulate power flow from an external adapter to the laptop battery and motherboard. Key Specifications & Features
When dealing with a laptop that does not charge, the OZ8682L is often a culprit. Use a multimeter to check the VINcap V sub cap I cap N end-sub (voltage input) to the chip.
: Essential for troubleshooting shorts or open circuits during board-level repairs.
