3.5.3
The Hall Switch Mode (HSM) within the TLE5012 allows to emulate the output of three Hall switches. Hall switches
are often used in electrical commutated motors to get information of the rotor position. With these three output
signals the motor will be commutated in the right way. Depending on the used pole pairs of the rotor, different
amount of electrical periods have to be realized. This is selectable within 0E
E1218 three polepairs and within the TLE5012-E1242 seven polepairs are fused.
output signals with the relationship between electrical angle and mechanical angle. The mechanical 0° point is
always used as reference.

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