Infineon TLE49462KHTSA1 High-Precision Differential Hall Effect Sensor for Automotive Applications

The Infineon TLE49462KHTSA1 represents a significant advancement in high-precision magnetic sensing technology, specifically engineered to meet the rigorous demands of modern automotive systems. As a differential Hall effect sensor, it is designed to provide accurate and reliable data for critical applications such as wheel speed sensing and transmission speed detection, which are fundamental to vehicle safety and performance.

A key feature of this sensor is its differential measurement principle. By utilizing two Hall elements spaced apart on a single silicon chip, the device effectively measures the magnetic differential field while simultaneously rejecting common-mode stray magnetic fields. This capability is crucial in the electrically noisy and magnetically harsh environment of an automobile, ensuring exceptional signal integrity and minimizing errors that could lead to system malfunctions.

The TLE49462KHTSA1 is characterized by its high accuracy and sensitivity, capable of detecting very small changes in magnetic fields. This allows for precise determination of rotational speed and direction, even at zero speed, which is vital for functions like Anti-lock Braking Systems (ABS) and Electronic Stability Programs (ESP). Its digital output provides a robust interface with microcontrollers, simplifying system design and enhancing reliability.

Furthermore, the device is built with automotive-grade quality and reliability. It operates over a wide temperature range from -40°C to 150°C, ensuring consistent performance under extreme conditions. Its integrated self-diagnostic functions contribute to higher functional safety levels, aligning with standards such as ISO 26262, making it an ideal choice for safety-critical applications.

Packaged in a robust and miniaturized SMD housing (PG-SSO-3-4), the sensor is optimized for automated assembly, reducing manufacturing costs while providing high resistance to mechanical stress and environmental influences.
