Sets the operational logic (High/Low trigger).
Basic flickering or timing sequences for decorative lighting.
Often used for manual override or left unconnected. VSS: Common return path. Common Applications yl105 datasheet
Receives signals from buttons or sensors (e.g., a steam sensor in a kettle).
If you are using the YL105 datasheet to repair a device, keep these points in mind: Sets the operational logic (High/Low trigger)
Monitoring voltage thresholds to prevent overcharging. Troubleshooting Tips
Extremely low (micro-ampere range in standby), making it ideal for energy-efficient "green" appliances. yl105 datasheet
If a timer isn't lasting the correct duration, the external capacitor connected to the timing pins has likely drifted in value or leaked.
