The OZ8682L is found on many laptop mainboards as the primary battery charging controller. For instance, in the motherboard, the IC is designated as PU911 . Similarly, in Lenovo IdeaPad 110 series devices, it appears as the OZ8682L charging chip.

The (also known as the OZ8682LN ) is a high-performance SMBus Battery Charger Controller manufactured by O2Micro . It is primarily designed for portable devices like laptops, tablets, and medical equipment that require precise power management.

The OZ8682L incorporates numerous advanced features that make it suitable for power‑sensitive portable designs. The following table summarises its most important attributes:

Connect an oscilloscope to the high/low-side gate drive paths. If the 8682L is alive, you should see clear, stable square-wave PWM pulses trying to activate the buck stage. If the gates sit at static 0V or VCC while ACOK is true, the driver stage inside the IC is compromised. Sourcing & Verification Authenticity
