Infineon Technologies TLI5012B GMR-Based Angle Sensor

Infineon Technologies TLI5012B GMR-Based Angle Sensor is a 360° angle sensor that detects the orientation of a magnetic field. This angle sensor achieves the detection by measuring sine and cosine angle components with monolithic integrated Giant Magneto Resistance (iGMR) elements. These raw signals (sine and cosine) are digitally processed internally to calculate the angular orientation of the magnetic field. The TLI5012B E1000 is a pre-calibrated sensor, and the calibration parameters are stored in laser fuses. This angle sensor communicates through a bi-directional Synchronous Serial Communication (SSC) that is SPI compatible.
