Sensor identity and bus fit
The TMP75CIDGKR is a digital local temperature sensor from Texas Instruments, outputting temperature data over an SMBus interface with 11-bit resolution.
Accuracy and temperature range
The sensing range matches the operating temperature envelope, so the same part can monitor a cold-start at -55°C and a hot soak at 125°C without derating the measurement.
Features for power-conscious designs
Built-in features include One-Shot conversion (for a single reading on demand), an output switch, programmable temperature limits, and a shutdown mode — the shutdown mode drops the quiescent current to near zero between measurements, useful for battery-powered or energy-harvesting nodes.
