Infineon TLE4997 Programmable Linear Hall Sensor for High-Precision Applications

The demand for highly accurate and reliable magnetic sensing solutions continues to grow across automotive, industrial, and consumer applications. Addressing this need, the Infineon TLE4997 stands out as a programmable linear Hall sensor engineered specifically for high-precision applications. This device combines advanced integration capabilities with exceptional performance, offering designers a flexible and robust solution for position and current sensing.

At the core of the TLE4997 is a sophisticated signal chain that includes a Hall plate, analog amplification, and a high-resolution analog-to-digital converter (ADC). This setup allows the sensor to deliver highly accurate analog and PWM output signals proportional to the applied magnetic flux. Its programmability is a key feature, enabling engineers to calibrate and customize parameters such as sensitivity, output characteristics, and temperature compensation through a serial interface (SSC). This flexibility ensures the sensor can be optimized for specific system requirements, enhancing overall performance and reducing calibration overhead.

The TLE4997 is designed to operate reliably in harsh environments. It supports a wide supply voltage range from 3.0 V to 5.5 V and offers outstanding temperature stability, critical for applications subject to extreme conditions. Additionally, the sensor incorporates comprehensive diagnostic functions and built-in protection mechanisms, including reverse polarity and overvoltage protection, which improve system safety and durability.

Typical applications include precise pedal position sensing in vehicles, throttle control, and current measurement in industrial systems. Its programmability and high accuracy also make it suitable for complex automation tasks and consumer electronics where miniaturization and efficiency are prioritized.
