Infineon XENSIV™ TLE49012 / TLI49012 Magnetic Angle Sensors

Introduction

The Infineon XENSIV™ TLE49012 and TLI49012 are high-precision digital magnetic angle sensors designed for fast and reliable rotational-position measurement. With ultra-low latency, integrated self-calibration, and flexible output options, these compact sensors support demanding motor-control and motion-sensing systems.

Part Description

The TLE49012 / TLI49012 family measures the angular position of a magnetic field and converts it into digital output data for a controller, inverter, or processing system. It supports both on-axis and off-axis magnetic measurement arrangements, giving designers flexibility when positioning the sensor and magnet within a mechanical assembly.

Key characteristics include:

• Ultra-low 1.5 µs latency for fast control-loop response
• Integrated self-calibration to help compensate for installation and magnetic-system variations
• High-precision magnetic angle measurement
• Available interface options including UVW, SPI, and ABZ + PWM
• Compact PG-VSON-8 package
• Suitable for automotive, industrial, robotics, and motor-control designs
• Digital outputs that simplify integration with microcontrollers, motor drivers, and control electronics

The availability of multiple output formats allows the sensor family to fit applications ranging from commutation-focused motor systems to high-resolution position-feedback solutions.
