Sends the signal to the load-switching component (Relay/Triac).
The YL105 is primarily categorized as a , frequently used in AC-powered appliances. It is designed to manage specific logic functions, such as auto-shutoff mechanisms or pulse-width modulation (PWM) for basic speed or heat control. Its popularity stems from its low power consumption and the minimal number of external components required to create a functional circuit. Key Specifications (Typical Values) yl105 datasheet
If you are using the YL105 datasheet to repair a device, keep these points in mind: the IC is likely fried. Conclusion
Use an oscilloscope or multimeter to see if Pin 6 (Output) toggles when the input trigger is activated. If the input changes but the output stays dead, the IC is likely fried. Conclusion yl105 datasheet
