STK672-440AN-E 2-phase Stepper Motor Driver

Ordering number : ENA2272 STK672-440AN-E Thick-Film Hybrid IC 2-phase Stepper Motor Driver http://onsemi.com Overview The STK672-440AN-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 fun.

Features

 Built-in overcurrent detection function, overheat detection function (output current OFF).
 FAULT1 signal (active low) is output when overcurrent or overheat is detected. The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 levels.
 Built-in power on reset function.
 A micro-step sine wave-driven driver can be activated merely by inputting an external clock.
 External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.
 The switch timing of the 4-phase distributor can be switched by setting an e.
