STK672-540: Motor Driver, 2-Phase, Full and Half Stepping, Unipolar

The STK672-540 is a unipolar fixed-current chopper type 2-phase stepping motor driver hybrid IC. It features power MOSFETs in the output stage and a build-in phase signal distribution IC. The incorporation of a phase distribution IC allows the STK672-540 to control the speed of the motor based on the frequency of an external input clock signal. It supports two types of excitation for motor control: 2-phase excitation and 1-2 phase excitation. It also provides a function for switching the motor direction.

特性
  • The motor speed can be controlled by the frequency of an external clock signal
  • The excitation type is switched according to the state of the MODE pin
  • A motor direction switching pin is provided.
  • Current detection resister is built in.
  • Hollow packages
优势
  • Easy to motor speed control
  • Easy to switch excitation type
  • Easy to switch a motor direction
  • Reduce the mounting area on PCB
  • Unlikely to release smoke or cause fires
