Infineon TLE4961-1K Hall-Effect Sensor: High-Precision Latch for Automotive and Industrial Applications

The demand for robust, reliable, and high-performance magnetic sensing solutions is paramount in modern automotive and industrial systems. Addressing this need, the Infineon TLE4961-1K stands out as a high-precision Hall-effect latch sensor engineered to deliver exceptional performance in the most demanding environments. This device exemplifies the integration of advanced semiconductor technology to provide accurate and dependable position and speed sensing.

As a latch-type Hall-effect sensor, the TLE4961-1K provides a defined digital output that switches on with a positive magnetic field and off with a negative one. This bi-stable characteristic makes it ideal for applications requiring precise detection of rotational movement, such as in brushless DC (BLDC) motor commutation, gear tooth speed sensing, and end-position detection. Its high magnetic sensitivity ensures accurate switching points, which are critical for maintaining system efficiency and timing.

A key strength of this sensor is its superior stability and reliability. It is specifically designed to withstand the harsh conditions typical of automotive applications. The device operates over a wide temperature range from -40 °C to 170 °C, ensuring consistent performance under the hood where temperatures can soar. Furthermore, it is highly resistant to mechanical stress, vibration, and common electrical disturbances like reverse voltage and overvoltage spikes, thanks to its integrated protection features.

The TLE4961-1K is also characterized by its low power consumption, a crucial factor for battery-operated systems and applications where energy efficiency is a priority. Despite its low power draw, it does not compromise on performance or response time. Its design incorporates a chopped Hall plate, which minimizes offset and compensates for the effects of mechanical stress and temperature drift, guaranteeing high precision over its entire operating life.

From electric power steering and transmission systems to industrial pumps and fans, the TLE4961-1K provides a critical sensing function that enhances overall system intelligence, safety, and efficiency. Its AEC-Q100 qualification underscores its suitability for automotive applications, giving designers confidence in its quality and longevity.
