LM73C1QDDCRQ1

Texas Instruments · Temperature Sensors · TSOT-23-6L

LM73C1QDDCRQ1 from Texas Instruments, in a TSOT-23-6L. 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 ADDR input Address select input: one of three device addresses is selected by connecting this pin to ground, leaving it floating, or connecting it to VDD (three-level CMOS logic input).
2 GND power_in Ground reference for the device.
3 VDD power_in Power supply voltage; the recommended supply range is 2.7 V to 5.5 V.
4 SMBCLK input SMBus serial clock input, operating up to 400 kHz and low-pass filtered (CMOS logic input).
5 ALERT output Open-drain digital output that goes active whenever the measured temperature exceeds a programmable temperature limit.
6 SMBDAT bidirectional SMBus bidirectional open-drain serial data signal, synchronous to SMBCLK and low-pass filtered.

CAD (KiCad official)

  • Symbol: LM73C1QDDCRQ1
  • Footprint: Package_TO_SOT_SMD:TSOT-23-6
  • 3D model: TSOT-23-6L (KiCad packages3D, STEP)
  • 3D model files: lm73c1qddcrq1-etched.step / lm73c1qddcrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm73c1qddcrq1.step / lm73c1qddcrq1.glb are the bare package body.
