Overview
The STK672-010 is a 4-phase stepping motor driver IC
that adopts power MOSFET for its output stage and that
uses a unipolar fixed-current chopper scheme. Since the
STK672-010 includes a built-in 4-phase distribution
controller, the stepping motor driver circuit and the control
scheme can be simplified, and the stepping motor driver
circuit structure can be standardized. The STK672-010
provides high torque, low vibration, and rapid response
based on a W1-2 phase excitation drive scheme. The
motor current is voluntary set from externals. Since,
compared to the earlier STK6770 Series, the STK672-010
has a smaller package size and reduced drive power
dissipation (reduced by 70% over previous products), it
provides a wider operating power supply voltage range.
Applications
Send/receive stepping motors in facsimile equipment
Stepping motor drive for paper feed and optical systems
in copier, and drum drive in laser beam printers
Pen drive in X-Y plotters
Industrial robots and other stepping motor application
products
Features
The STK672-010 can easily implement stepping motor
drive applications with the provision of a DC power
supply and a clock pulse oscillator.
<4-Phase Distribution Controller>
The STK672-010 supports four excitation types selected
by the excitation mode setting (M1 and M2).
1. 4-phase 1 excitation
2. 4-phase 1-2 excitation
3. 4-phase 2 excitation
4. 4-phase W1-2 excitation
Schmitt input pins (for a high noise margin)
Controller inputs are CMOS compatible (with built-in
pull-up resistors), thus allowing direct control from I/O
ports or special-purpose controller LSIs.
An interval is set up during mutual switching of the AA
and BB phase output signals in 4-phase 2 excitation
mode.
<Driver Circuits>
Since the STK672-010 is a separate excitation type
circuit, it supports a wide operating power supply
voltage range. (V
CC
1 = 5 to 42 V)
Current detection resistors are provided within the
hybrid IC.
Drive power reduced by 70% when compared to the
STK6770 Series (at 1 A drive).
Can provide a motor drive current of up to 1.7 A without
a heat sink.
