Infineon TLE4917: A High-Performance Hall Effect Sensor for Precision Applications

The demand for reliable and precise magnetic sensing solutions continues to grow across industries such as automotive, industrial automation, and consumer electronics. Addressing this need, the Infineon TLE4917 stands out as a high-performance, ultra-low-power Hall effect switch designed for accuracy and durability in demanding applications.

Uncompromising Precision and Reliability

At its core, the TLE4917 is engineered to provide exceptional magnetic switching accuracy. It features a well-defined, programmable BOP/BRP (Operate and Release Point) hysteresis, which is crucial for suppressing noise and preventing erroneous switching in environments with vibration or electrical interference. This ensures stable and reliable operation, making it ideal for position sensing, speed detection, and end-point detection where precision is non-negotiable.

Ultra-Low Power Consumption

A defining characteristic of the TLE4917 is its ultra-low power consumption. Utilizing a sophisticated duty-cycling mechanism, the sensor intelligently alternates between active measurement phases and sleep modes. This dramatically reduces the average current draw to mere microamps, enabling its use in battery-powered and energy-sensitive applications without compromising performance or lifetime.

Robustness for Demanding Environments

Infineon has built the TLE4917 to withstand harsh conditions. It offers outstanding ESD (Electrostatic Discharge) protection and a wide operating voltage range. Furthermore, its design is highly resistant to mechanical stress and temperature fluctuations, ensuring consistent performance from -40 °C to 170 °C. This robustness makes it a perfect fit for automotive applications like gearbox sensors, brake pedals, and door contact switches.

Integrated Protection Features

The sensor incorporates comprehensive diagnostic and protection features. Reverse voltage protection safeguards the device against accidental incorrect wiring, while its resistance to environmental stressors like humidity and contamination enhances its long-term reliability. This integrated protection simplifies system design and reduces the need for additional external components.
