Functional safety grading combined with easy-to-use concept

Functional safety applications in cars often require substantial system design efforts. With XENSIV TLE5014, Infineon Technologies is now launching a new magnetic angle sensor family that is both ready for these demanding applications and at the same time easy to use. At the Sensor+Test 2018 fair in Nuremberg (26th-28th June), Infineon will demonstrate how easily the new products can be integrated into a safety-critical Electric Power Steering system (EPS).

The TLE5014 sensors meet ISO26262 ASIL C for the single die and ISO26262 ASIL D for the dual die versions. Therefore, all products are ready for applications with the highest functional safety requirements.

The TLE5014 sensors show an extremely small angle error of less than 1° across the entire temperature profile and lifetime. This is particularly helpful in applications with the need for very accurate position sensing such as steering angle sensing or motor commutation. Further application areas range from EPS and pedal position sensing to any other kind of position measurement.

All XENSIV TLE5014 angle sensors are available as single and dual die products. All products come pre-configured and pre-calibrated as plug-and-play sensors - and are thus easy to use. Today, customers can choose between the interfaces SENT, PWM and SPC.

Infineon will launch additional versions with an SPI interface by the end of this year. On top of those protocol options, the sensors can be adapted to any kind of application setup via their programmable E²PROM interfaces.

The XENSIV TLE5014 sensors are based on giant magnetoresistive (GMR) technology with the sensor unit and the logic part monolithically integrated on one single chip. All products are capable of high input voltages up to 26V.
