LM73CIMKX-0

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

LM73CIMKX-0 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 three-level CMOS input to ground, leaving it floating, or connecting it to VDD.
2 GND power_in Ground reference pin for the device.
3 VDD power_in Power supply input; the recommended operating supply range is 2.7 V to 5.5 V.
4 SMBCLK input SMBus serial clock input that operates up to 400 kHz and is low-pass filtered.
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 line, synchronous to SMBCLK and low-pass filtered.
