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 | I2C/SMBus serial data. Open-drain output, requires external pull-up resistor to VDD. Supports bus speeds up to 1MHz (fast mode) and 2.3MHz (high-speed mode). |+| 2 | SCL | input | I2C/SMBus serial clock input. Open-drain, requires external pull-up resistor to VDD. |+| 3 | ALT | output | Over-temperature alert output. Open-drain; asserts when the measured temperature crosses the programmed T_OS/T_HYST thresholds. Requires an external pull-up resistor. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | A2 | input | I2C slave address select bit 2. Must be tied to GND or VDD to set one of eight possible bus addresses. |+| 6 | A1 | input | I2C slave address select bit 1. Must be tied to GND or VDD to set one of eight possible bus addresses. |+| 7 | A0 | input | I2C slave address select bit 0. Must be tied to GND or VDD to set one of eight possible bus addresses. |+| 8 | VDD | power_in | Positive supply input, 1.4V to 5.5V (3.3V nominal). Absolute max 6V. Decouple with a local bypass capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | MSOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `LM75BDPDP`++## CAD (KiCad official)++- Symbol: `LM75BDP`+- 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/lm75bdp-datasheet.pdf) (20 pp, sha256 `68957518e9fd34d5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
