LM75BDP

UMW · Temperature and Humidity Sensor · MSOP-8

LM75BDP from UMW, in a MSOP-8. 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.

Ordering variants

Same part, different packaging or reel option.

  • LM75BDP

CAD (KiCad official)

  • Symbol: LM75BDP
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm75bdp-etched.step / lm75bdp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm75bdp.step / lm75bdp.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm75bdp.step 123 KB You want the bare part, or you mark your own boards.
lm75bdp-etched.step 1.4 MB You want the part with LM75BDP already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 362 faces against 147 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UMW datasheet (20 pp, sha256 68957518e9fd34d5, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
