# M601W

**Mysentech** · Temperature Sensors · DFN-8(2x2)

M601W from Mysentech, in a DFN-8(2x2). 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 | VDD | power_in | Supply pin; the datasheet gives an operating supply range of 1.8 V to 5.5 V (typical 3.3 V). |
| 2 | ALERT | output | Alarm indicator output whose level changes when the measured temperature crosses the programmed high or low alarm thresholds; the datasheet specifies an output drive of IOH = 1 mA at VDD = 5 V. |
| 3 | DQ | bidirectional | Single-wire digital bus interface requiring an external pull-up of 1 kΩ to 10 kΩ (4.7 kΩ typical); VIL max 0.3×VDD, VIH min 0.7×VDD, and VOL max 0.4 V at IOL = 3 mA. |
| 4 | NC | unconnected | Not connected; leave floating or connect to ground. |
| 5 | GND | power_in | Ground reference pin. |
| 6 | NC | unconnected | Not connected; leave floating or connect to ground. |
| 7 | NC | unconnected | Not connected; leave floating or connect to ground. |
| 8 | NC | unconnected | Not connected; leave floating or connect to ground. |
