Infineon TLE49SRx Magnetic Angle Sensors

Featuring a wide availability for automotive, industrial and consumer applications

Infineon's TLE49SRx portfolio is a family of stray field robust angle sensors based on Hall technology for measuring absolute angular position in the range from 0° to 360°. The sensor provides digital output interfaces. Spatially separated Hall cells, which enable a stray field robust measurement of the magnetic field, and signal conditioning circuits are implemented on the integrated circuit (IC).

Infineon's portfolio of XENSIV™ angular sensors comprises single and dual-channel solutions suitable for all types of automotive, industrial, and consumer rotation applications. Our high-precision sensors are available with AMR, GMR, and TMR sensor technology.

The sensor supports PWM, SENT and SPC interfaces and is developed according to ISO 26262 as safety element out of context.

Largest Variety of Magnetic Angle Sensor ICs With xMR Technologies

Angular position sensors measure sine and cosine angle components with monolithically integrated magneto-resistive elements to detect the orientation of an applied magnetic field. In simple terms, angle sensors are a type of magnetic rotary sensor, which measure the rotational movement of mechanical elements using the data to control and correct the operation of components. Magnetic angular position sensors are used to provide exact rotor position data to optimize motor control, torque, and efficiency in automotive applications, such as steering or braking systems, industrial applications like robotics, and consumer applications like gimbals.

Infineon’s broad portfolio of XENSIV™ sensor solutions includes high-precision magnetic angle sensors with AMR (anisotropic magneto-resistive), GMR (giant magneto-resistive), and TMR (tunnel magneto-resistive) sensor technologies.
