The rotor is aligned to a certain position specified in DC excitation mode for the period of (a), during which
the IP pin voltage decreases from Vrefout to 0.5 V. The time constant for the period is determined by C

mode is switched to the sensorless square-wave mode.
DC excitation time
Duty cycle is determined by the gradient of SC terminal voltage, which depends on the charging of a
capacitor.
This voltage is clamped when the output duty cycle reaches about 35% for the de-excitation and
over-current protection.
When CW = U-phase → V-phase
When CCW = U-phase → W-phase
Ta (typ.) = 2.3 × C
Forced commutation time
The forced commutation is started when the IP pin voltage falls below to 0.5 V or lower.
The output duty cycle of forced commutation is determined by V
