Infineon TLI5012BE1000XUMA1 High-Resolution Magnetic Angle Sensor for Precision Motion Control Applications

In the rapidly advancing fields of industrial automation, robotics, and automotive systems, the demand for precise and reliable motion control has never been greater. At the heart of many of these sophisticated systems lies a critical component: the angle sensor. The Infineon TLI5012BE1000XUMA1 stands out as a premier solution, engineered to deliver exceptional performance in high-accuracy applications.

This sensor is a high-resolution, contactless magnetic angle encoder based on Giant Magneto-Resistance (GMR) technology. The core principle of its operation involves detecting the orientation of a magnetic field generated by a simple two-pole magnet that rotates above the sensor IC. This contactless nature is a key advantage, eliminating mechanical wear and tear and ensuring long-term reliability and durability, even in harsh operating environments.

The TLI5012BE1000XUMA1 offers an outstanding 16-bit resolution per revolution (65536 positions), providing system designers with the extremely fine angular data necessary for ultra-precise positioning and smooth motion control. This high resolution is complemented by excellent accuracy, with a typical angle error of less than ±0.5° over the full temperature range. Furthermore, it supports a wide range of rotational speeds, making it suitable for both low-speed high-torque and high-speed applications.

A significant feature of this sensor is its integrated Safety Integrity Level (SIL) compliance. It is designed to meet the requirements of SIL2/SIL3 according to the IEC 61508 standard, which is paramount for functional safety in automotive and industrial applications. Built-in diagnostic functions continuously monitor the system for faults, such as magnet loss or signal integrity issues, enhancing the overall safety and robustness of the end product.

The sensor provides multiple output interfaces to seamlessly integrate into various system architectures. These include a Synchronous Serial Interface (SSI), a Pulse Width Modulation (PWM) output, and an incremental interface (IIF/EnDat), offering designers flexibility and simplifying the design-in process.

Typical applications that benefit from its capabilities include:

High-performance servo drives and motors

Robotic joint control and articulated arms

Steer-by-wire and electric power steering (EPS) systems

Industrial encoders and rotary knobs

Heavy-duty construction equipment

ICGOODFIND: The Infineon TLI5012BE1000XUMA1 is a top-tier magnetic angle sensor that sets a high benchmark for precision motion control. Its combination of high 16-bit resolution, inherent robustness from contactless sensing, and integrated functional safety features makes it an indispensable component for developers building the next generation of reliable and high-accuracy automated systems.
