Manufacturer: onsemi

Overview: Ordering number : ENA0755A STK672-600 Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi.com Overview The STK672-600 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications • Office photocopiers, printers, etc.

Key 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 MODE1 pin (low or high).
  • The excitation mode is set at the rising edge of the clock signal when the MODE2 pin is high, or at the rising edge or falling edge when the MODE2 pin is low.
  • The phase is maintained even if the excitation mode is switched in the middle of operation.
