SGM809-RXN3

SGMICRO · Supervisor And Reset ICs · SOT-23

SGM809-RXN3 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 supervisory circuit.
2 RESET output Active-low push-pull reset output on the SGM809; it remains low while VCC is below the reset threshold and for 240ms (TYP) after VCC rises above the threshold.
3 VCC power_in Power supply voltage that is monitored; the RESET output remains operational with VCC as low as 1V and the device is specified from 1.2V to 5.5V over -40°C to +125°C.
