8682l Datasheet New! Jun 2026

: Monitors both the current drawn from the AC adapter and the current fed into the battery to prevent system-wide overcurrent scenarios.

The 8682L IC is a versatile component that can be used in a wide range of applications, including:

When a power brick is connected, the 8682L monitors the voltage via its input logic. If the input exceeds the under-voltage lockout (UVLO) threshold, the chip asserts the ACOK signal. The internal state machine then reads commands from the SMBus lines.

: Prioritizes power to the host system. If the system demands more current, the 8682L dynamically throttles the battery charging rate to prevent the AC adapter from overloading. Technical Specifications & Absolute Maximum Ratings

Due to the QFN-16 package, the PCB layout must account for adequate heat dissipation via a central thermal pad.

: The center thermal pad of the QFN chip must be directly soldered to a solid copper fill on the PCB. Multiple thermal vias should bridge this pad to underlying internal ground planes to pull heat away efficiently. The internal state machine then reads commands from

N-channel switching transistors to handle peak power transfer efficiently.

: It regulates voltage and current for charging, ensuring safe and efficient energy transfer to the battery. SMBus Interface
