STK672-040-E

DRIVER, MOTOR, STEPPER, 45VIN, 1.5A.

The STK672-040-E is a stepping motor driver Hybrid IC uses power MOSFETs in the output stage. It includes a built-in microstepping controller and is based on unipolar constant-current PWM system. It supports application simplification and standardization by providing a built-in 4-phase distribution stepping motor controller. It supports five excitation methods of 2-phase, 1 to 2 phase, 1W 2 phase, 2W 1 to 2 phase and 4W 1 to 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.
