Product Summary

The STK673-010 is a 3-Phase Stepping Motor Driver with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage. The STK673-010 includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit. Applications of the STK673-010 include transmission and reception in a facsimile, optical system in a copying machine and industrial machines or products.
