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 | SDA | bidirectional | Serial data line for the SMBus / I2C interface. Open-drain; requires an external pull-up resistor to V+. |+| 2 | SCL | input | Serial clock input for the SMBus / I2C interface. Open-drain; requires an external pull-up resistor to V+. Supports fast mode up to 400 kHz and high-speed mode up to 2.75 MHz. |+| 3 | ALERT | output | Over-temperature alert output. Open-drain; requires an external pull-up resistor. Asserts when the measured temperature crosses the programmed T_HIGH / T_LOW thresholds. |+| 4 | GND | power_in | Ground return for the device. Connect to system ground. |+| 5 | A2 | input | I2C slave address select bit A2. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits. |+| 6 | A1 | input | I2C slave address select bit A1. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits. |+| 7 | A0 | input | I2C slave address select bit A0. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits. |+| 8 | V+ | power_in | Positive supply voltage input, 1.4 V to 5.5 V (absolute maximum 6 V). Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | MSOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `TMP175AIDGKRIDGKR`+- `TMP175AIDGKRIDGK`+- `TMP175AIDGKRIDR`+- `TMP175AIDGKRID`++## CAD (KiCad official)++- Symbol: `TMP175AIDGKR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/tmp175aidgkr-datasheet.pdf) (18 pp, sha256 `da5f7606e5f3ffd5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
