Dual Die Angle Output

The bottom sensor element of the TLE5012BD is flipped relative to the orientation of the top sensor element

Therefore the rotation direction sensed by the bottom element is opposite to the top element. This is advantageous

for safety critical applications, as the two sensor elements do generally not output the same angle. Figure 3-1

shows the output of the two sensor ICs for a given external magnetic field orientation.

Figure 3-1 Dual die angle output

For applications where an identical angle output of both ICs is desired, the rotation direction and angle offset of

one sensor IC can be reconfigured by changing the settings in the ANG_BASE and ANG_DIR registers via SSC

interface.
