Ordering number : ENA2137 STK672-401C-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi.com Overview The STK672-401C-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 • Entry of external clock is enough to activate the micro step sinu.
• 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 operation.
• The motor current is set by a voltage divider formed by an external resistor connected to the Vref pin.
• The CLK input pin is .
