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 8682l ic datasheet
: Acts as a battery charge controller that communicates via the SMBus protocol to manage multi-cell battery charging.
The dual-wire SMBus serial clock and data interface line.
In the vast world of integrated circuits, part numbers that begin with "86" often relate to power management, voltage regulation, or audio amplification. The is one such component that has garnered attention among electronics engineers, hobbyists, and repair technicians. While not as globally documented as mainstream chips from Texas Instruments or Analog Devices, the 8682L serves a critical role in specific consumer electronics, particularly in portable devices, power banks, and audio equipment.
Finding a full public PDF datasheet for the 8682L can be challenging because it is often a discontinued or proprietary part. For hardware repair, it is frequently compared with the EA3059QDR for parametric compatibility.

Operating as an SMBus Level 2 smart charger, the 8682L acts upon digital commands originating directly from either the host system micro-controller or a smart battery pack. Instead of using hardwired analog resistor dividers to establish the baseline voltage and terminal current limits, the system dynamically updates these targets via digital registries. This software-driven malleability allows the IC to seamlessly change charging parameters on the fly, tailoring its performance to specific state-of-charge (SoC) parameters or temperature curves.
