KP235XTMA1: Infineon's High-Performance Linear Hall Sensor for Precision Applications

In the realm of precision sensing, the ability to accurately measure magnetic fields is paramount for a vast array of applications, from automotive systems to industrial automation. Addressing this critical need, Infineon Technologies introduces the KP235XTMA1, a state-of-the-art linear Hall sensor engineered for exceptional performance and reliability. This device sets a new benchmark for precision, providing designers with a robust solution for the most demanding environments.

At its core, the KP235XTMA1 translates magnetic flux density into a precise, proportional analog output voltage. Unlike digital switches, this linear output provides continuous data on the position, distance, or strength of a magnetic field, enabling nuanced control and measurement. The sensor operates over a wide supply voltage range from 3.0 V to 5.5 V, making it compatible with both 3.3 V and 5 V systems, a crucial feature for versatile design integration.

A standout feature of the KP235XTMA1 is its outstanding accuracy and sensitivity. It boasts a very low noise output and excellent stability over temperature, ensuring consistent performance even under fluctuating operational conditions. This is further enhanced by its integrated temperature compensation circuitry, which automatically corrects for drift, guaranteeing highly reliable and precise measurements from -40 °C to 125 °C. This makes it ideally suited for under-the-hood automotive applications like throttle valve sensing, pedal positioning, and transmission systems, where extreme temperatures are a constant challenge.

Beyond automotive, its precision is invaluable in industrial settings for tasks such as linear actuator feedback, valve control, and fluid level sensing. The device is also characterized by its ultra-low power consumption, which is critical for battery-powered portable equipment and always-on sensing nodes in the Internet of Things (IoT).

The sensor is housed in a compact and robust SOT-23 package, offering mechanical durability while minimizing the required PCB space. Furthermore, it includes built-in protection mechanisms against reverse polarity and overvoltage conditions, enhancing system-level robustness and longevity.

ICGOODFIND: The Infineon KP235XTMA1 emerges as a superior choice for engineers seeking a high-performance linear Hall sensor. Its compelling combination of high precision, excellent temperature stability, wide operating voltage, and robust design makes it an indispensable component for advancing precision in automotive, industrial, and consumer applications.
