STK672-070-E集成电路（IC）的电机驱动器控制器规格书PDF中文资料

Overview

The STK672-070-E is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage. It includes a builtin microstepping controller and is based on a unipolar constant-current PWM system. The STK672-070-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.

This product is provided in a smaller package than SANYOs earlier STK672-040-E for easier mounting in end products.
