utput Current: 2.8 A (No Heat Sink*) Unipolar constant-current chopper (external excitation PWM) circuit with built-in microstepping controller Overview The STK672-080 is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage. It includes a built-in microstepping controller and is based on a unipolar constant-current PWM system. The STK672-080 supports application simplification and standardization by providing a built-in 4 phase distribution stepping motor controller.
