Ordering number : ENN7441A
Thick-Film Hybrid IC
STK672-060
Stepping Motor Driver (Sine Wave Drive) Output Current: 1.2 A (No Heat Sink*)
Unipolar constant-current chopper (external excitation PWM) circuit with built- in microstepping controller
Overview
The STK672-060 is a stepping motor driver hybrid IC that adopts power MOSFETs in its output stage. It features a built-in microstepping controller that implements unipolar constant current PWM drive. Since this IC includes a 4-phase distribution controller for stepping motors, it can contribute not only to system simplification but to circuit standardization as well.
