Stepping Motor Driver (Sine Wave Drive) Output Current: 1.2 A (No Heat Sink*)

Overview
The STK672-060 is a stepping motor driver hybrid IC that adopts power MOSFETs in its output stage. It features a built-in microstepping controller that implements unipolar constant current PWM drive. Since this IC includes a 4-phase distribution controller for stepping motors, it can
contribute not only to system simplification but to circuit standardization as well.
The STK672-060 supports the 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitation (drive) methods and can control the motor with the basic stepping angle of the stepping motor divided into up to 16 divisions. Motor rotation can also be controlled with just
the clock signal.

FEATUREs
• The STK672-060 can implement a stepping motor drive system with just the provision of a DC power supply and a clock pulse generator.
The excitation mode settings (M1, M2, and M3) select one of five excitation methods.
• 2 phase excitation
• 1-2 phase excitation
• W1-2 phase excitation
• 2W1-2 phase excitation
• 4W1-2 phase excitation

Applications
• Facsimile unit stepping motor drive for both transmission and reception
• Paper feed and optical system stepping motor drive in copiers
• Laser printer drum drive
• Printer carriage stepping motor drive
• X/Y plotter pen drive
• Other stepping motor applications
