STMicroelectronics · Supervisor And Reset ICs · SOT-23-3
STM1812MWX7F from STMicroelectronics, in a SOT-23-3. 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 | RST | output | Active-high reset output (push-pull) that pulses high when VCC drops below VRST and remains high for minimum 100 ms after VCC rises above the reset threshold. |
| 2 | VCC | power_in | Supply voltage input for reset threshold monitor; operating range 1.2 V to 5.5 V for -40 to 105°C. |
| 3 | VSS | power_in | Ground reference for power supply; must be connected to system ground. |
