SKT672-040-E Stepping Motor Driver

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 ou.

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: circular mode, one inside mode, and two outside modes.
• Phase retention even if excitation is switched.
• The excitation phase sta.
