Unipolar stepper board is high efficient stepper driver for Unipolar stepper motor been design for various application like CNC, robotics, control routers, lathes, mills, PCB drillers and engravers.

STK672-050 is a unipolar constant-current choppertype externally-excited 4-phase stepping motor driver hybrid IC which uses MOSFET power devices. It has a microstep operation-supported 4-phase distributed controller built-in to realize a high torque, low vibration, low noise stepping motor driver using a simple control circuit.


• Microstep sine-wave driver operation using only an external clock input (0.2Ωcurrent detection resistor built-in) • Microstep drive using only an external reference voltage setting resistor • 2, 1-2, W1-2, 2W1-2, 4W1-2 phase excitation selectable using external pins • Selectable vector locus (perfect circle mode, inside 1 mode, outside 2 modes) to match motor characteristics in microstep drive state • Phase hold function during excitation switching • Schmitt trigger inputs with built-in pull-up resistor (20kΩ) • Monitor output pin enabling real-time confirmation of IC excitation • The CLK and RETURN inputs provide an internal noise elimination circuit as well as CMOS Schmitt circuit to prevent malfunction due to impulse noise. • 4-phase distribution switch timing selected externally to either CLK rising-edge only detection mode or both rising-edge and falling-edge detection mode • ENABLE pin for excitation current cutoff, thereby reducing system current drain when driver is stopped

STK672-050-E motor driver. The STK672-050-E is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage. It includes a built in microstepping controller and is based on a unipolar constant current PWM system. The STK672-050-E supports application simplification and standardization by providing a built in 4 phase distribution stepping motor controller. It supports five excitation methods 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitations, and can provide control of the basic stepping angle of the stepping motor divided into 1/16 step units. It also allows the motor speed to be controlled with only a clock signal. The use of this hybrid IC allows designers to implement systems that provide high motor torques, low vibration levels, low noise, fast response, and high efficiency drive.
