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

Unipolar constant-current chopper (external excitation PWM) circuit with built- in microstepping controller

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.

This hybrid IC can implement highly efficient drive with

high motor torque, low vibration, low noise, and fast

response. As compared to the earlier Sanyo STK672-010

series, the STK672-060 features a smaller package, fewer

required external components, and improvements to the

controller for high functionality high performance

microstepping drive.

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

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.

<Control Block Features>

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
