STK672-060

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. The STK672-060 supports the 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitation (drive) methods and can control the motor with the basic stepping angle of the stepping motor divided into up to 16 divisions. Motor rotation can also be controlled with just the clock signal. This hybrid IC can implement highly efficient drive with high motor torque, low vibration, low noise, and fast response. As compared to the earlier Sanyo STK672-010 series, the STK672-060 features a smaller package, fewer required external components, and improvements to the controller for high functionality high performance microstepping drive.
