1.1 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 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).
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
be seen in Chapter 7.
Online diagnostic functions are provided to ensure reliable operation.
