Texas Instruments TMP464 Remote & Local Temperature Sensor

Texas Instruments TMP464 Remote and Local Temperature Sensor is a high-accuracy, low-power temperature sensor using a two-wire, SMBus, or I²C compatible interface. Up to four 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. The TMP464 device provides high accuracy (0.75°C) and high resolution (0.0625°C) measurement capabilities. The device supports low voltage rails (1.7V to 3.6V), common two-wire interfaces, and is available in a small, space-efficient package (3mm×3mm) for easy integration into computing systems.
