2-Phase Stepping Motor Driver 19-Pin HZIP

The STK672-410C-E is a hybrid IC for use a unipolar, 2-phase stepping motor driver with PWM current control. It includes a built-in microstepping controller and is based on a unipolar constant-current PWM system. The STK672-410C-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. And the STK672-410C-E is a new version of STK672-410. It has high stability for a steep change of the logic voltage in comparison with STK672-410.
