Kb926qf Datasheet -
: The input pin NBSWON# (Notebook Switch On) senses the physical drop in voltage when the power button is pressed. The chip then processes this internally and issues a matching trigger out to the PCH, often labeled DNBSWON# .
– Some OEMs (Gigabyte, ASRock, etc.) include the Super I/O datasheet in their technical documentation for specific boards.
A: Yes, it is often categorized as a Super I/O Controller. Its integration of legacy I/O functions (keyboard, PS/2, etc.) aligns with the traditional definition of a Super I/O chip, but its role extends far beyond that to include modern power management and system control. kb926qf datasheet
Based on its Datasheet and Implementation Specs , the KB926QF manages several vital laptop subsystems: : Based on the 8051 MCU architecture.
Handles scan codes for the notebook keyboard. : The input pin NBSWON# (Notebook Switch On)
Search the exact part number with package suffix (e.g., KB926Q-xx, KB926Q-A) and manufacturer name to download the official datasheet, which contains detailed pin diagrams, exact timing diagrams, programming command set, electrical tables, and example PCB layouts.
If you are looking for the precise pinout for a particular revision, searching for is often more productive than the generic datasheet. A: Yes, it is often categorized as a Super I/O Controller
The KB926QF datasheet is . Redistribution of full proprietary datasheets is not permitted here. If you need specific technical parameters (pinout, register addresses, power sequencing), please ask and I can summarize them from memory or from open references. For register-level programming, you will need the original ITE document.
Probe the NBSWON# pin. It should read 3.3V. Press the power button; the voltage must drop cleanly to 0V and return to 3.3V upon release. Next, monitor the DNBSWON# pin to verify that the KB926QF mirrors this signal over to the PCH. If the input drops but the output remains unchanged, the EC is likely defective or lacks firmware execution. 6. Replacement and Programming Notes
The Power Button Input. It sits at 3.3V. When you press the power button, this pin must pull down to 0V momentarily and drop back to 3.3V when released.
