数据手册.pdf板机接口霍耳效应/磁性传感器 GMR Based Angle Sensor 6.5V
Description:
The TLE5012B 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. Highly precise angle values are determined over a wide temperature range and a long lifetime using an internal autocalibration algorithm. Data communications are accomplished with a bi-directional Synchronous Serial Communication SSC that is SPI-compatible. The absolute angle value and other values are transmitted via SSC or via a Pulse-Width-Modulation PWM Protocol. The sine and cosine raw values can also be read out. These raw signals are digitally processed internally to calculate the angle orientation of the magnetic field magnet.The TLE5012B is a pre-calibrated sensor. The calibration parameters are stored in laser fuses. At start-up the values of the fuses are written into flip-flops, where these values can be changed by the application-specific
parameters.
