Hall Switch Mode

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 0EH (HSM_PLP). Within the TLE5012-

E0318 three pole pairs are fused; within the TLE5012-E0742, seven pole pairs are fused. Figure 23 depicts the

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.

Hall Switch Mode

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