Description for the TMP464

The TMP464 device 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. 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 four 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 TMP464 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) for easy integration into computing systems. The remote junction supports a temperature range from –55°C to +150°C. The TMP464 has a preprogrammed temperature limit of 125°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
