Infineon TLV4906K: High-Precision 3D Magnetic Sensor for Absolute Angle and Position Sensing

The Infineon TLV4906K represents a significant advancement in magnetic sensing technology, offering a highly integrated solution for accurate angular and positional measurements. Designed to meet the rigorous demands of modern automotive, industrial, and consumer applications, this sensor leverages 3D Hall technology to deliver exceptional performance in a compact package.

At the core of the TLV4906K is its ability to measure magnetic field components along three perpendicular axes (X, Y, Z). This enables the device to calculate absolute angular position with high accuracy, typically within ±0.5° in optimized conditions, without requiring direct physical contact. The sensor operates across a wide magnetic field range and is immune to misalignment errors common in planar Hall solutions, making it ideal for applications where precision is critical.

Key features include integrated signal processing, which provides directly digitized output via a standard SPI interface, reducing the need for external components and simplifying system design. The device also includes built-in diagnostics and robust protection against reverse polarity, overvoltage, and ESD, ensuring reliability in harsh environments. With a low power consumption profile, it is suitable for both battery-powered and always-on systems.

Typical applications range from electric power steering and throttle control in vehicles to brushless DC motor commutation and rotary knobs in industrial equipment. Its ability to function reliably in the presence of external disturbances, such as temperature variations and mechanical stress, underscores its versatility.

In summary, the Infineon TLV4906K sets a new standard for magnetic sensors by combining high precision, 3D sensing capability, and system-level integration in a single device.
