STK672-120-SL-E - 2-phase Stepping Motor Driver

Key Features

  • The motor speed can be controlled by the frequency of an external clock signal (the CLOCK pin signal).
  • The excitation type is switched according to the state (low or high) of the MODE pin. The mode is set to 2-phase or 1-2phase excitation on the rising edge of the clock signal.
  • A motor direction switching pin (the CWB pin) is provided.
  • All inputs are schmitt inputs and 40kΩ (typical:.
  • 50 to +100%) pull-up resistors are built in.
  • The motor.

Ordering number : ENA2140 STK672-120-SL-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi.com Overview The STK672-120-SL-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications • Office photocopiers, printers, etc. Features • The motor speed can be controlled by the frequency of an external clock signal (the CLOCK pin signal). • The excitation type is switched according to the state (low or high) of the MODE pin. The mode is set to 2-phase or 1-2phase excitation on the rising edge of the clock signal. • A motor direction switching pin (the CWB pin) is provided. • All inputs are schmitt inputs and 40kΩ (typical: –50 to +100%) pull-up resistors are built in.
