STK672-050-E

Overview

The STK672-050-E is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage. It includes a built-

in microstepping controller and is based on a unipolar constant-current PWM system. The STK672-050-E supports

application simplification and standardization by providing a built-in 4 phase distribution stepping motor controller. It

supports five excitation methods: 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitations, and can

provide control of the basic stepping angle of the stepping motor divided into 1/16 step units. It also allows the motor speed

to be controlled with only a clock signal.

The use of this hybrid IC allows designers to implement systems that provide high motor torques, low vibration levels, low

noise, fast response, and high-efficiency drive.

Applications

• Facsimile stepping motor drive (send and receive)

• 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

Note*: Conditions: VCC1 = 24V, IOH = 2.0A, 2W1-2 excitation mode.
