Overview
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 monolithically
i
ntegrated 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).
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 to application-specific
parameters. The precision of the angle measurement, over a wide temperature range and a long lifetime, can be
improved by enabling an optional 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 four other interfaces are available with the TLE5012B: Pulse-Width-Modulation (PWM) Protocol,
Short-PWM-Code (SPC) Protocol, Hall Switch Mode (HSM) and Incremental Interface (IIF). These interfaces can
be used in parallel with SSC or alone. Pre-configured sensor derivates with different interface settings are also
available. See the derivate ordering codes in the
TLE5012B Data Sheet
. A description of the derivates can also

Online diagnostic functions are provided to ensure reliable operation.
