Overview
The TLE5012BD is a fully redundant 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 TLE5012BD 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.
Online diagnostic functions are provided to ensure reliable operation.
