TMP126EDCKRQ1

Texas Instruments · Temperature and Humidity Sensor · SC-70-6

TMP126EDCKRQ1 from Texas Instruments, in a SC-70-6. 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 CS input Active-low chip select input for activating the SPI interface. Logic levels are 0.3VDD (VIL) / 0.7VDD (VIH) referenced to VDD (1.62V to 5.5V).
2 GND power_in Ground reference for the device. Connect to system ground.
3 SIO bidirectional Bidirectional SPI data line (system input/output). Combines MOSI/MISO on a single 3-wire SPI data pin. VOH ≥ VDD-0.4V at IOH=3mA; VOL ≤ 0.4V at IOL=-3mA.
4 SCLK input SPI serial clock input from the host controller. Logic levels 0.3VDD / 0.7VDD.
5 ALERT output Active-low open-drain alert output that asserts on programmable temperature-limit or slew-rate events. May be left floating or tied to ground if unused. VOL ≤ 0.4V at IOL=-3mA (open-drain - external pull-up required).
6 VDD power_in Positive supply voltage input. Recommended 1.62V to 5.5V (typ. 3.3V). Decouple with 0.1µF to GND close to the pin.

CAD (KiCad official)

  • Symbol: TMP126EDCKRQ1
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SC-70-6 (KiCad packages3D, STEP)
  • 3D model files: tmp126edckrq1-etched.step / tmp126edckrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmp126edckrq1.step / tmp126edckrq1.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (48 pp, sha256 5ea601e612668d75, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
