3.5.3
The Hall Switch Mode (HSM) within the TLE5012 makes it possible to emulate the output of three Hall switches.
Hall switches are often used in electrical commutated motors to get information about the rotor position. With these
three output signals, the motor will be commutated in the right way. Depending on which pole pairs of the rotor are
used, various electrical periods have to be utilized. This is selectable within 0E
E0318 three pole pairs are fused; within the TLE5012-E0742, seven pole pairs are fused.
three output signals with the relationship between electrical angle and mechanical angle. The mechanical 0° point
is always used as a reference.
The HSM is generally used with open-drain output, but it can be changed to push-pull within SSC_OD and
IFAB_OD.

The HSM Interface can be selected by connecting CLK to GND, and CSQ has to be logic “1”.
