概要

XENSIV™ - TLI5012B E1000 angle sensor iGMR, economic with SPI compatible interface

The Infineon TLI5012B E1000 is an 360° angle sensor that detects the orientation of a magnetic field, achieved 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 angle orientation of the magnetic field (magnet).

Our TLI5012B E1000 is a pre-calibrated sensor, 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.
Further precision of the angle measurement over a wide temperature range and a long lifetime are improved with the internal autocalibration algorithm.

Data communications are accomplished with a bi-directional Synchronous Serial Communication (SSC) that is SPI-compatible.The sensor configuration is stored in registers, which are accessible by the SSC interface.
Additionally the TLI5012B E1000 has Incremental Interface (IIF).
