TMP6431QDYATQ1 Description

Short technical summary and product information.

The Texas Instruments TMP6431QDYATQ1 is a silicon-based, Automotive Grade linear thermistor designed for precise temperature sensing and compensation. It offers a positive temperature coefficient (PTC) with a linear resistance change across its operating temperature range.

 

Key electrical specifications include a nominal resistance of 47 kΩ at 25°C, with a tight tolerance of ±1% between 0°C and 70°C. The device boasts a high sensitivity with a TCR of 6400 ppm/°C at 25°C and a typical TCR tolerance of 0.2% across the temperature range. It also features a fast thermal response time of 0.6 seconds.

 

Designed for demanding automotive applications, the TMP6431QDYATQ1 operates from -40°C to 150°C, meeting AEC-Q100 Grade 0 standards. It includes built-in fail-safe features for short-circuit conditions and exhibits robust performance with a typical long-term sensor drift of 0.5%.

 

This thermistor is available in a SOT-5X3 package, suitable for surface mount applications. Its linear characteristics and consistent sensitivity simplify temperature conversion methods, making it ideal for thermal compensation in display backlights and battery management systems, as well as thermal threshold detection in motor control and power electronics.
