STK672-440BNGEVB: Motor Driver, 2-Phase, Microstepping, Unipolar Evaluation Board
The STK672-440BNGEVB is an Evaluation Board for the STK672-440A-E, a hybrid IC for unipolar, 2-phase stepping motor driver with PWM current control. The device includes a built-in microstepping controller and is based on a unipolar constant-current PWM system. The STK672-440A-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. In addition the STK672-440A-E has various protective function against over-current and over-heat.
