): Generally supports between , depending on the thermal management of the PCB. Low On-Resistance (
While an official datasheet from a specific manufacturer is definitive, the following table represents the for devices matching the 8682l designation in repair and design communities.
The reveals a sophisticated, highly integrated SMBus Level 2 Battery Charger Controller. Its combination of Hybrid Power Boost technology, >95% efficiency, and a comprehensive set of programmable protections made it a popular choice for portable computer OEMs in the early 2010s. 8682l Datasheet
: If the application involves high-frequency switching nearby, add an LC filter or additional bulk capacitance to the input rail. 4. Assembly and Soldering The fine-pitch QFN package requires careful handling. Reflow Profile
| Substitute Part | Key Difference | When to Use It | | :--- | :--- | :--- | | | Higher max current (800mA), larger package (SOT-223) | When needing >300mA. Not pin-compatible with SOT-23. | | XC6206P332MR | Ultra-low quiescent current (1µA), same pinout (SOT-23) | For battery-powered upgrades. Direct substitute for 3.3V variant. | | 78L05 | Standard dropout (1.7V), TO-92 package only | For older through-hole designs, but dropout is much worse. | | MCP1700-3302E | Very low quiescent (1.6µA), SOT-23 | Modern replacement for 3.3V 8682l in low-power IoT. | ): Generally supports between , depending on the
: The bidirectional data line responsible for handling instructions on target charging currents and voltage ceilings. 3. High-Frequency Switching Control (Buck Converter)
The QFN-16 package has 4 pins per side and a central ground pad for heat dissipation. Its combination of Hybrid Power Boost technology, >95%
Operating as an SMBus slave, it accepts command protocols from the host Embedded Controller (EC) or Super I/O chip (such as the common IT8985E or KB9022Q series found on laptops). It converts digital commands into highly accurate analog pulse-width modulation (PWM) gate drive signals. Pin Configuration Overview
Before diving into raw numbers, it’s crucial to understand what the 8682l likely is. Based on component naming conventions and common industry databases, the is most frequently associated with:
The output voltage is set by the ratio of two resistors connected to the FB pin. The RT8682L typically has an internal reference voltage ($V_REF$), usually .
