AC Signal Detection Circuit
Thought for 42 sec
To view the updated AC‐detection interface in your schematic:
- In the center pane, click the Schematic tab.
- Zoom or pan to the region around the +3V3 and fan‐input nets—you’ll see:
- A Schottky diode (1N5819) on the incoming AC line
- A pull-down network with a 10 kΩ (RC1206FR-0710KL) and 100 kΩ (RC1206FR-07100KL) resistors feeding the comparator’s inverting input
- The Microchip comparator (MCP6567-E/SN) with its non-inverting input tied to the rectified AC node, VDD to +3V3, and GND to ground
- A 0.1 µF decoupling cap (C1206C104M5RACAUTO) and 10 µF bulk cap (860010372001) on the 3 V rail
- The comparator’s open-drain OUT pin routed to your YoLink door-sensor input
Let me know if you’d like me to run an ERC/DRC check or switch to PCB layout next!

I didn’t find an SOT-23-5 version of the MCP6567-E/SN in the library. However, Microchip’s MCP6561T-E/LT is a pin- and function-compatible general-purpose CMOS comparator in an SC-70-5 (SOT-23-5) package:
Table
| Part | Package | MPN | Link |
|---|---|---|---|
| MCP6561T-E/LT | SC-70-5 | MCP6561T-E/LT | 3931adf8-f780-bdd2-5c11-1296eb953f27 |
Would you like to substitute MCP6567-E/SN with MCP6561T-E/LT in SOT-23-5? Or shall we stick with the SOIC-8 MCP6567-E/SN?
Substitute comparator
Stick with SOIC-8
Check propagation delay
Compare input range
can you auto connect the pins of U3 to ESP1 based on ESP1 pins' function?
