The IC is physically marked as "8682L" on the top of the chip.
: The QFN-16 package requires a PCB layout that allows for adequate heat dissipation. 8682l ic datasheet
The 8682L employs a rather than a PMOS. This classic bipolar design offers inherent protection against reverse input voltages but comes with a higher quiescent current than modern CMOS LDOs. The internal block diagram reveals: The IC is physically marked as "8682L" on
: Verify that Pin 1 (DCIN) is receiving the target voltage from the adapter socket. Ensure Pin 3 (ACOK) outputs a high signal, indicating the system recognizes the input voltage as stable. If you are currently debugging a board or
If you are currently debugging a board or engineering a product around this component, the most productive next step is to evaluate the external components surrounding the IC. Ensure you verify the , as even a slight shift in resistance from a voltage surge will cause incorrect power readings and trigger false overcurrent protection routines. Share public link
For design engineers, the OZ8682L offers programmable voltage and current limits, dual high‑side current sensing, and simplified SMBus control. For repair technicians, understanding the IC’s role in laptop charging circuits, its typical external components, and common failure modes is essential for effective troubleshooting.
