39 / 50 page  TLE5012B Specification Data Sheet 39 Rev. 2.0, 2014-02 4.4.4 Hall Switch Mode (HSM) The Hall Switch Mode (HSM) within the TLE5012B makes it possible to emulate the output of 3 Hall switches. Hall switches are often used in electrical commutated motors to determine the rotor position. With these 3 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 controlled. This is selectable within 0EH (HSM_PLP). Figure 4-17 depicts the three output signals with the relationship between electrical angle and mechanical angle. The mechanical 0° point is always used as reference. The HSM is generally used with push-pull output, but it can be changed to open-drain within the register IFAB_OD. Sensors with preset HSM are available as TLE5012B E3005. Figure 4-17 Hall Switch Mode The HSM Interface can be selected via SSC (IF_MD = 010). Table 4-23 Hall Switch Mode Parameter Symbol Values Unit Note / Test Condition Min. Typ. Max.
