STK672-401C-E - 2-phase Stepping Motor Driver

Key Features

  • Entry of external clock is enough to activate the micro step sinusoidal driver.
  • The excitation mode of 2, 1-2, W1-2, 2W1-2, or 4W1-2 can be selected with the external pin.
  • The 4-phase distributor switching timing can be set to occur either on both rising and falling edge detection or on rising edge detection only with an external pin (MODE3).
  • A phase holding function is provided to prevent phase skip during switching of excitation in the course of operatio.
