TMR-Based Angle Sensor
Application Circuits
1 Application Circuits
The application circuits in this chapter show the various connection possibilities of the TLE5501. It can be used
in a single ended mode (only one sine and one cosine signal,
Figure 1 and Figure 3 ) and in a differential mode
with a total of four output signals ( Figure 2 and Figure 4 ).
To fully implement the safety concept of the TLE5001 E0002 version and achieve highest diagnostic coverage,
the four output signals have to be sampled singled ended. This is necessary, as the proposed external safety
mechanisms in the Safety Manual act on the single ended signals. Nevertheless, to reach highest angle
accuracy, the differential calculated angle shall be used for the application. The single ended signals are for
diagnostic only.
