PRODUCTION DATA. TMP451-Q1 SLOS877A – OCTOBER 2014 – REVISED JANUARY 2019 TMP451-Q1 ±1°C remote and local temperature sensor with η-factor and offset correction, series-resistance cancellation, and programmable digital filter 1 1 Features 1 • Qualified for Automotive Applications • AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to 125°C Ambient Operating Temperature Range • ±1°C Accuracy for Local and Remote Diode Sensors • 0.0625°C Resolution for Local and Remote Channels • 1.7-V to 3.6-V Supply and Logic Voltage Range • 27-µA Operating Current, 3-µA Shutdown Current • Series Resistance Cancellation • η-Factor and Offset Correction • Programmable Digital Filter • Diode Fault Detection • Two-Wire and SMBus™ Serial Interface • 8-Pin WSON (WDFN) Package 2 Applications • Automotive Infotainment Systems • ECU Processor Temperature Monitoring • TCM Processor Temperature Monitoring • BCM Processor Temperature Monitoring • LED Headlight Thermal Control 3 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 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.
