Hybrid Motor Driver ICs
STK672 Series – STK672-040-E/050-E/060-E
The STK672 series of hybrid motor driver ICs use power MOSFETs in the output stage and are used to
drive stepper motors. Based on a uni-polar constant-current PWM system, the devices include a built-in
microstepping controller and support five excitation methods: 2 phase, 1-2 phase, W1-2 phase, 2W1-2
phase and 4W1-2 phase. In addition, they can provide control of the basic stepping angle of the stepping
motor divided into 1/16 step units and allow 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, fast response and high efficiency drive.
