4 Stepper Motor Control

The main features of the MSPM0 Stepper Motor Control designs include:

  • 4-PWM stepper control up to 100 kHz using full- or half-stepping, or 1-PWM stepper control up to 500 kHz using 1/256 microstepping
  • Spin or step motor in open loop based on selected step size
  • Voltage reference for current limiting
  • SPI interface to configure driver settings and diagnose driver faults (SPI devices only)
  • Fault detection using fault pin
