SGM809-RXN3L from SGMICRO, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground / device return. |
| 2 | RESET | output | Active-low reset output (push-pull on SGM809). RESET is driven low while VCC is below the 2.63V (TYP) reset threshold, and remains low for 240ms (TYP) after VCC rises above the threshold. Output is valid with VCC as low as 1V. |
| 3 | VCC | power_in | Power supply voltage that is monitored by the reset comparator. Operating range 1.0V to 5.5V (TA = 0-70°C); absolute max 6V. Supply current typ 13µA at VCC < 3.6V. |
