The Texas Instruments TMP9R00-SP device is a radiation-hardened, multi-zone, high-accuracy, low-power temperature sensor.

It uses a two-wire, SMBus, or I2C compatible interface. The device monitors up to eight remote and one local temperature zones simultaneously, aggregating the temperature measurements in a system and reducing design complexity. Typical use cases are monitoring the temperature of different high-power devices, such as MCUs, GPUs, ADCs, DACs and FPGAs.

Advanced features such as series resistance cancellation, programmable ideality factor, temperature offset correction, and temperature limits are included to provide a robust thermal monitoring solution.

Each remote channel and the local channel have two independently programmable thresholds that trigger when the corresponding temperature exceeds the limit. A programmable hysteresis setting is available to avoid toggling around the threshold.
