M1601W from Mysentech, 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 | VDD | power_in | Positive supply input. Operating range 1.8V to 5.5V (absolute max -0.3V to 6V). Typical supply current 0.1µA idle (single-shot mode), 4.8µA average at 1 measurement/s, 450µA peak during conversion. |
| 2 | DQ | bidirectional | 1-Wire single-bus digital interface (open-drain). Requires external pull-up resistor (typ. 4.7kΩ, 1kΩ recommended for long cables or multi-drop). Carries all ROM/function commands, temperature data, and CRC. VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD, VOL ≤ 0.4V @ IOL = -3mA. |
| 3 | GND | power_in | Device ground reference. Connect to system ground plane. |

3D model downloads
Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
m1601w.step |
59 KB | You want the bare part, or you mark your own boards. |
m1601w-etched.step |
1.1 MB | You want the part with M1601W already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 273 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
