Overview
The STK672-080-E is a stepping motor driver hybrid IC that uses power
MOSFETs in the output stage.
It includes a built-in microstepping controller and is based on a unipolar constant-current PWM system.
The STK672-080-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 phas...
