Thick-Film Hybrid IC
STK672-080
Stepping Motor Driver (Sine Wave Drive) Output Current: 2.8 A (No Heat Sink*)
Unipolar constant-current chopper (external excitation PWM) circuit with built-in microstepping controller
Overview
The STK672-080 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 STK672-080
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.
Compared to the earlier SANYO STK672-050, the
STK672-080 features a significantly smaller package for
easier mounting in end products.
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
Features
• Can implement stepping motor drive systems simply by
providing a DC power supply and a clock pulse
generator.
<Control Block Features>
• One of five drive types can be selected with the drive
mode settings (M1, M2, and M3)
—2 phase excitation drive
—1-2 phase excitation drive
—W1-2 phase excitation drive
—2W1-2 phase excitation drive
—4W1-2 phase excitation drive
• Phase retention even if excitation is switched.
• The MOI phase origin monitor pin is provided.
• The CLK input counter block can be selected to be one of
the following by the high/low setting of the M3 input pin.
—Rising edge only
—Both rising and falling edges
Note*: Conditions: VCC1 = 24 V, IOH = 2.0 A, 2W1-2
excitation mode.
