Overview
The STK673-010-E is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar
constant current PWM system, in which a power MOSFET is employed at an output stage.
It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor
driver circuit.
The number of motor revolution can be controlled by the frequency of external clock input. 2, 2-3, W2-3 and 2W2-3-phase
excitation modes are available. The basic step angle of the stepping motor can be separated as much as one-eighth 2-3-
phase to 2W2-3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise.
Applications
As a 3-phase stepping motor driver for transmission and reception in a facsimile.
As a 3-phase stepping motor driver for feeding paper feed or for an optical system in a copying machine.
Industrial machines or products employing 3-phase stepping motor driving.
Features
Number of motor revolution can be controlled by the frequency of external clock input.
4 types of modes, i.e., 2, 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising of
clock signals, by switching Highs and Lows of Mode A and Mode B terminals.
Setting a Mode C terminal Low allows an excitation mode that is based on rising and falling of a clock signal.
By setting the Mode C terminal Low, phases that are set only by Mode A and Mode B can be changed to other phases as
follows without changing the number of motor revolution: 2-phase may be switched to 2-3-phase; 2-3-phase may be
switched to W2-3-phase; and W2-3-phase may be switched to 2W2-3-phase.
Phase is maintained even when the excitation mode is changed.
