Overview
The TLE5012 is a 360° angle sensor that detects the orientation of a magnetic field. This is achieved by measuring sine and cosine angle components with monolithic integrated Giant Magneto Resistance (iGMR) elements.
High precision angle values are achieved over temperature and lifetime using internal autocalibration algorithm.
Data communications are accomplished with a bi-directional SSC Interface that is SPI compatible.
