**STMicroelectronics** · Monitors & Reset Circuits · SOT-23

STM1061N31WX6F from STMicroelectronics, 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 | OUT | output | Active-low open drain output that goes low when VCC drops below VTH- and remains low while VCC is below VTH- + VHYST, with a pull-up to any supply up to 6V. |
| 2 | VSS | power_in | Ground, the reference for the power supply, which must be connected to the system ground. |
| 3 | VCC | power_in | Supply voltage and input for the voltage detector, specified from 0.7V to 6.0V. |
