http://onsemi.com
Overview
The STK672-532 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.
Applications
• Office photocopiers, printers, etc.
Features
• The motor speed can be controlled by the frequency of an external clock signal. • 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high). • The phase is maintained even if the excitation mode is switched in the middle of operation. • The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction
of rotation. • Supports schmitt input for 2.5V high level input.
