Overview

Ordering number : ENA2297 STK672-632AN-E Thick-Film Hybrid IC 2-phase Stepper Motor Driver http://onsemi.
com 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.
 Incorporating a current detection resistor (0.
141Ω: resistor tolerance 2%), motor current can be set using two external resistors.
 The ENABLE pin can be used to cut output current while maintaining the excitation mode.
 With a wide current setting range, power consumption can be reduced during standby.
  No motor sound is generated during hold mode due to external excitation current control.
  Supports compatible pins with STK672-630AN/-640AN/-642AN-E.
