Infineon XENSIV™ TLx49012 Digital Angle Sensors Enable Unique System Self-Calibration

Infineon Technologies AG introduced the XENSIV™ TLx49012 on September 28, 2026, a family of four digital angle sensors based on Hall technology. These sensors are specifically engineered for demanding motor control applications within both the automotive and industrial sectors. The family's key differentiators, highlighted by Infineon, include its unique system self-calibration capability, high angle accuracy, low latency, flexible mounting options, and diverse interface choices, all crucial for modern motor control system designers.

This product introduction directly addresses the growing adoption of brushless DC motors across various automotive platforms and the rapid expansion of the robotics market. Infineon emphasizes that these trends necessitate angle sensors with high accuracy, minimal latency, and straightforward design-in processes. The TLx49012 family is designed to meet these evolving requirements while simultaneously simplifying the integration of angle sensing into complex motor control systems.

The core differentiating feature of the XENSIV™ TLx49012 family is its integrated system self-calibration function. This innovative capability eliminates the need for customers to develop their own calibration routines and removes the reliance on external reference encoders. Infineon states that this approach significantly reduces development effort and associated costs throughout the entire product lifecycle, from initial system design to end-of-line testing. Furthermore, the sensors support fully automatic initial calibration and continuous on-chip compensation, which facilitates both on-axis and off-axis mounting configurations without adding calibration complexity, offering system designers greater flexibility in sensor placement.

The TLx49012 sensor family delivers an impressive angle accuracy of less than 0.1° and a low latency of 1.5 µs. It supports a magnetic field range from 20 mT to 120 mT, which Infineon notes ensures compatibility with standard magnet configurations prevalent across motor platforms in both target markets. To ensure broad compatibility with various motor controller architectures, the family offers multiple interface options, including SPI, ABZ, UVW, and PWM. The product line includes automotive-qualified TLE49012 variants, which are ISO 26262 compliant and achieve ASIL B, alongside TLI49012 variants tailored for industrial applications. Both the TLE49012 automotive variants and TLI49012 industrial variants are currently available.
