SGM809B-RXN3LG 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. |
| 2 | nRESET | output | Active Low Reset output; remains low while VCC is below the reset threshold and remains low for 240ms (TYP) after VCC rises above the reset threshold. |
| 3 | VCC | power_in | Power Supply voltage that is monitored. |
