8681l Ic Datasheet

Forum posts indicate the OZ8681LN is used as a in notebook motherboards. One user reported encountering the IC in the smart charging stage of a Positivo notebook, while another referenced it in relation to a Haswell‑based laptop motherboard. In these contexts, the IC is labeled simply as "8681L" on the PCB, complicating identification.

The power dissipation rating is based on the IC mounted on a specified 20.0 × 10.0 × 0.8mm³ paper-phenol circuit board. 8681l ic datasheet

The (most commonly known as the O2Micro OZ8681L or OZ8681LN ) is a highly advanced battery charge controller chip . It is widely used in portable computer systems like Lenovo IdeaPad laptops to manage power safely. When a laptop will not turn on or charge, this chip is often the main cause of the problem. Understanding its datasheet helps repair technicians fix broken motherboard circuits. What is the 8681L IC?

Feedback Input. Connects to a resistor divider to set output voltage. COMP

: The 8681L may not be outputting gate drive signals to the charging MOSFETs, or its AC-detect circuitry has failed.
