HE61CN3302MR from HEERMICR, in a SOT-23-3. 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 | VOUT | output | NMOS open-drain detector output for the N-type part, Hi-Z when VDD>VDET(+) and pulled to VSS when VDD≤VDET(-). |
| 2 | GND | power_in | Ground (VSS) reference pin for the voltage detector. |
| 3 | VIN | power_in | Supply and detection voltage input (VDD), operating voltage 0.7V to 10V per electrical characteristics, absolute maximum -0.3V to 8V. |
