STK672-622A-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 FAULT1 signal (active low) is output. The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 levels.
  • Built-in power on reset function.
  • The motor speed is controlled by the frequency of an external clock signal.
