AEC-Q100 qualified dual die angle sensor detects the orientation of a magnetic field

Rutronik is offering the dual die 360-degree angle sensor TLE5012BD. The device from Infineon is designed for angular position sensing in automotive applications such as steering angle measurements, electrical commutated motors or general angular sensing. It identifies the orientation of a magnetic field by measuring cosine and sine angle components with monolithic iGMR elements. The device is fully redundant with two sensor ICs in a single package. It concludes highly precise angle values over a broad temperature range and a long lifetime using an internal autocalibration algorithm. 360-degree angle measurement is carried out with revolution counter and angle speed measurement. The absolute angle value and other values are broadcasted via SSC or via a PWM Protocol. The cosine and sine raw values can also be read out. These signals are digitally processed internally to calculate the angle orientation of the magnetic field (magnet). Data communications are performed with a bi-directional SSC that is SPI-compatible. The device is a pre-calibrated sensor. The calibration parameters are saved in laser fuses. At start-up, the values of the fuses are written into flip-flops, where they are able to be changed by the application-specific parameters. The sensor supports SIL with online diagnostic functions and status information to ensure reliable operation.
