TMP451AQDQFRQ1 General Description

The TMP451-Q1 device is a high-accuracy, low-power remote temperature sensor monitor with a built-in local temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors or diodes that are integral parts of microprocessors, microcontrollers, or FPGAs. The temperature is represented as a 12-bit digital code for both the local and the remote sensors, giving a resolution of 0.0625°C. The temperature accuracy is ±1°C (maximum) in the typical operating range for the local and the remote temperature sensors. The two-wire serial interface accepts the SMBus communication protocol.

Advanced features such as series resistance cancellation, programmable nonideality factor (η-factor), programmable offset, programmable temperature limits, and a programmable digital filter are combined to provide a robust thermal monitoring solution with improved accuracy and noise immunity.

The TMP451-Q1 device is ideal for multi-location, high-accuracy temperature measurements in a variety of automotive sub-systems. The TMP451-Q1 is available in a Wettable Flanks WSON package that provides a visual indicator of solderability to lower automatic visual inspection (AVI) time. The device is specified for operation over a supply voltage range of 1.7 V to 3.6 V and a temperature range of –40°C to 125°C.
