2.1 Minimizing Motor Startup Time

In this application note, startup time is defined as the time taken for the motor to spin from 0% to 100% input speed duty cycle. The MCT8316A provides four different motor startup methods as listed below:

  • Align
  • Double align
  • Initial Position Detection (IPD)
  • Slow first cycle

For applications that require quick startup time, it is recommended choosing either Align or Initial Position Detection (IPD) as the startup method.
