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.
Features of STK672-050 3Amp Unipolar 6 Wires Stepper Motor Driver:
• Microstep sine-wave driver operation using only an
external clock input (0.2Ωcurrent detection resistor
• Microstep drive using only an external reference voltage
• 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
• Monitor output pin enabling real-time confirmation of
• 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.
