Overview

Ordering number : EN5227D STK672-040-E Thick-Film Hybrid IC Unipolar Constant-current Chopper (external excitation PWM) Circuit with Built-in Microstepping Controller Stepping Motor Driver (sine wave drive) Output Current 1.5A (no heat sink*) http://onsemi.com Overview The STK672-040-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 STK672-040-E supports application simplification and standardization by providing a built-in 4 phase distribution stepping motor controller.

Key Features

Can implement stepping motor drive systems simply by providing a DC power supply and a clock pulse generator.
One of five drive types can be selected with the drive mode settings (M1, M2, and M3) 1) 2 phase excitation drive 2) 1-2 phase excitation drive 3) W1-2 phase excitation drive 4) 2W1-2 phase excitation drive 5) 4W1-2 phase excitation drive.
Provides four freely selectable modes for the vector locus during microstepping drive: circula.
