SGM809-SXN3 from SGMICRO, 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 | GND | power_in | Ground reference pin for the supervisor, listed as Ground in the pin description table. |
| 2 | RESET | output | Active-low reset output that remains low while VCC is below the reset threshold and for 240ms (TYP) after VCC rises above the threshold; the SGM809 has a push-pull output. |
| 3 | VCC | power_in | Power supply voltage that is monitored by the device. |
