Overview
The STK673-011-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 2W2-3phase excitation modes are available.
The basic step angle of the stepping motor can be separated as much as one-eighth 2-3-phase ...
