CH412SR from COSEMITECH, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply voltage pin, operating range 3.5V to 30V with reverse-battery protection (absolute maximum 40V, reverse -40V). |
| 2 | OUT | output | Open-collector output pin, sinks up to 20 mA operating (absolute maximum 50 mA, -0.3V to 40V), turns low at Bop and high at Brp. |
| 3 | GND | power_in | Ground pin. |
