TMP468AIRGTT Allgemeine Beschreibung

The TMP468 device is a multi-zone, high-accuracy, low-power temperature sensor using a two-wire, SMBus or I²C compatible interface. Up to eight remote diode-connected temperature zones can be monitored simultaneously in addition to the local temperature. Aggregating the temperature measurements across a system allows improved performance through tighter guard bands and can reduce board complexity. A typical use case is for monitoring the temperature across different processors, such as MCUs, GPUs, and FPGAs in complex systems such as servers and telecommunications equipment. Advanced features such as series resistance cancellation, programmable non-ideality factor, programmable offset, and programmable temperature limits are included 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 that are 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 device provides high accuracy (0.75°C) and high resolution (0.0625°C) measurement capabilities. The device supports low voltage rails (1.7 V to 3.6 V), common two-wire interfaces, and is available in a small, space efficient package (3 mm × 3 mm or 1.6 mm × 1.6 mm) for easy integration into computing systems. The remote junction supports a temperature range from –55°C to +150°C.
