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.

The HSM Interface can be selected via SSC (IF_MD = 010).
