TMP431DDGKT

Texas Instruments · Temperature Sensors · VSSOP-8-0.65mm

TMP431DDGKT from Texas Instruments, in a VSSOP-8-0.65mm. 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 V+ power_in Power supply, positive (2.7 V to 5.5 V)
2 DXP input Analog positive connection to remote temperature sensor
3 DXN input Analog negative connection to remote temperature sensor
4 THERM output Digital thermal flag, active low, open-drain; requires pullup resistor to V+
5 GND power_in Ground
6 ALERT/THERM2 output Digital alert (reconfigurable as second thermal flag), active low, open-drain; requires pullup resistor to V+
7 SDA bidirectional Bidirectional digital serial data line for SMBus, open-drain; requires pullup resistor to V+
8 SCL input Digital serial clock line for SMBus, open-drain; requires pullup resistor to V+

CAD (KiCad official)

  • Symbol: TMP431DDGKT
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)
  • 3D model files: tmp431ddgkt-etched.step / tmp431ddgkt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmp431ddgkt.step / tmp431ddgkt.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (50 pp, sha256 78d1a87f0972ed9f, retrieved 2026-10-03, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-4-5-20251001 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
