Six-step driving method with BEMF zero crossing detection
The BEMF zero crossing information can be used to evaluate the rotor position; in this way
no Hall effect sensors or encoder are needed.
In six-step driving mode one of the three phases is left in high impedance state.
Comparing the voltage of this phase with the center-tap voltage we can detect the BEMF
zero-crossing.
In shown example (see Figure 16), the OUT1 phase voltage is monitored by the CP+; the
center-tap voltage is obtained as combination of three phase voltages and monitored by the
CP- pin. Only when the OUT1 is in high impedance, the CPOUT will perform a commutation
each time a BEMF zero crossing is detected.
In this configuration one sense resistor is needed, the three OUT pins are connected
together to RSENSE.
