8 / 32 page TLE5009 Functional Description Data Sheet 8 Rev. 1.1, 2012-04 2 Functional Description 2.1 General The GMR sensor is implemented using vertical integration. This means that the GMR sensitive areas are integrated above the analog portion of the TLE5009 chip. These GMR elements change their resistance depending on the direction of the magnetic field. Four individual GMR elements are connected in a Wheatstone bridge arrangement. Each GMR element senses one of two components of the applied magnetic field: • X component, Vx (cosine) or the • Y component, Vy (sine) The advantage of a full-bridge structure is that the amplitude of the GMR signal is doubled and temperature effects cancel out. Figure 1 Sensitive bridges of the GMR sensor Note: In Figure 1, the arrows in the resistors symbolize the direction of the reference layer. Size of the sensitive areas is greatly exagerated for better visualisation. The output signal of each bridge is unambiguous in a range of 180°. Therefore two bridges are oriented orthogonally to each other to measure 360°. With the trigonometric function ARCTAN, the true 360° angle value that is represented by the relation of X and Y signals can be calculated according to Equation (1).
