STK672-543-E - 2-phase Stepping Motor Driver

Features

  • The motor speed can be controlled by the frequency of an external clock signal.
  • 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high).
  • The phase is maintained even if the excitation mode is switched in the middle of operation.
  • The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction of rotation.
  • Supports schmitt input for 2.
