STMicroelectronics · Supervisor And Reset ICs · SOT-23
STM1813LWX7F 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 | RST | bidirectional | Active-low open-drain reset output with an internal 5.5 kΩ pull-up (3.1 kΩ to 7.5 kΩ) and push-button/manual reset detect; it pulses low when VCC drops below VRST or when RST is held low for at least 1.5 µs, and stays low for at least tPBRST (100 ms min.) after release. |
| 2 | VCC | power_in | Supply voltage and input for the reset threshold monitor, specified from 1.0 V to 5.5 V (0 °C to +105 °C) or 1.2 V to 5.5 V (-40 °C to +105 °C), with absolute maximum of -0.3 V to 7.0 V. |
| 3 | VSS | power_in | Ground and the reference for the power supply, which must be connected to the system ground. |
