(specifically brands like Apple and Acer), the chip's robustness makes it suitable for various embedded systems. WIT Computers
If the input voltage is correct but ACOK remains low (pulled down to 0V), the internal voltage comparators inside the IC may be damaged, or the input potential divider resistors have drifted out of spec.
The most critical design parameter for the 8682L is the programming resistor connected between and GND. The formula is:
: This component is moisture-sensitive. It must be baked at 125°C for 24 hours before reflow soldering to remove any absorbed moisture. This step prevents the "popcorning" effect where rapid heating causes internal damage to the chip.
Look for “8682L” directly or codes like “82L”, “68L”, or “L82” – many Chinese ICs use shorthand laser marking. 8682l ic datasheet
The 8682L is most commonly housed in a package. Below is the standard pin configuration derived from multiple field extractions and partial datasheets.
Note: Always consult the specific for your device’s motherboard layout to verify exact pin functionality. 3. Application Areas
Pins for regulating the charging current and voltage.
Always consult the specific manufacturer's datasheet for guaranteed min/typical/max values. (specifically brands like Apple and Acer), the chip's
The “L” suffix often denotes a low-power or low-quiescent-current version, optimized for battery-powered applications.
: Automatically detects AC adapter voltage and outputs valid adapter presence and discharge current signals to the system. Applications The OZ8682L is commonly found in:
The system recognizes the power adapter, but the charge state remains stuck permanently at "0%, plugged in, not charging".
Occasionally, the 8682L appears in an 8-pin package with additional pins for thermal pad (exposed pad for heat dissipation) and dual LED drive outputs. Always verify the top marking. The formula is: : This component is moisture-sensitive
When dealing with a laptop that does not charge, the OZ8682L is often a culprit. Use a multimeter to check the VINcap V sub cap I cap N end-sub (voltage input) to the chip.

In real-world repair forums, the 8682L has been asked about in relation to the IC8681L . One user inquired if the 8682L is compatible with the IC8681L , but without a datasheet for either, a definitive answer could not be given. This highlights the importance of having the correct datasheet to compare pinouts and electrical characteristics. Using an IC cross-reference tool, which can search a database of millions of components, is the recommended approach to find a verified form-fit-function equivalent part. For example, the UP1589q and RT8239b have been suggested as possible equivalents for some applications, but this should be verified against the specific original IC's datasheet.
