Overview

The STK672-040 is a unipolar constant-current chopper-

type externally-excited 4-phase stepping motor driver

hybrid IC which uses MOSFET power devices. It has a

microstep operation-supported 4-phase distributed con-

troller built-in to realize a high torque, low vibration, low

noise stepping motor driver using a simple control circuit.

Applications

• Printer, copier, and X-Y plotter stepping motor drivers

• Microstep sine-wave driver operation using only an

• Microstep drive using only an external reference voltage

• 2, 1-2, W1-2, 2W1-2, 4W1-2 phase excitation selectable

• Selectable vector locus (perfect circle mode, inside 1

• Phase hold function during excitation switching

• Schmitt trigger inputs with built-in pull-up resistor
