Overview
The STK672-632AN-E is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control.
Applications
Office photocopiers, printers, etc.
Features
Built-in overcurrent detection function, overheat detection function (output current OFF). FAULT signal (active low) is output when overcurrent or overheat is detected. Built-in power on reset function. The motor speed is controlled by the frequency of an external clock signal.
2 phase or 1-2 phase excitation switching function.
Phase is maintained even when the excitation mode is switched.
Rotational direction switching function. Supports schmitt input for 2.5V high level input.
