The TMP468 device is amulti-zone, high-accuracy, low-power temperature sensor using atwo-wire, SMBus or I2C compatible interface. Up toeight remote diode-connectedtemperature zones can be monitored simultaneously in addition to the local temperature. Aggregatingthe temperature measurements across a system allows improved performance through tighter guardbands and can reduce board complexity. A typical use case is for monitoring the temperature acrossdifferent processors, such as MCUs, GPUs, and FPGAs in complex systems such as servers andtelecommunications equipment. Advanced features such as series resistance cancellation,programmable non-ideality factor, programmable offset, and programmable temperature limits areincluded to provide a robust thermal monitoring solution with improved accuracy and noise immunity.
Each of the eight remote channels (and the local channel) can be programmed independently with two thresholds thatare triggered when the corresponding temperature is exceeded at the measured location. In addition,there is a programmable hysteresis setting to avoid constant toggling around the threshold.
The TMP468 deviceprovides high accuracy (0.75°C) and high resolution (0.0625°C) measurement capabilities. The devicesupports low voltage rails (1.7 V to 3.6 V), common two-wire interfaces, and is available in asmall, space efficient package (3 mm × 3 mm or 1.6 mm × 1.6 mm) foreasy integration into computing systems. The remote junction supports a temperature range from–55°C to 150°C.
