STK672-630A-E - 2-phase Stepping Motor Driver

Features

  • Built-in overcurrent detection function (output current OFF).
  • Built-in overheat detection function (output current OFF).
  • If either over-current or overheat detection function is activated, the FAULT signal (active low) is output.
  • Built-in power on reset function.
  • The motor speed is controlled by the frequency of an external clock signal.
  • 2 phase or 1-2 phase excitation switching function.
  • Using either or both edges of the cloc.
