STK672-640CN-E - 2-phase Stepper Motor Driver

Features

  • Built-in motor terminal open detection function(output current OFF). There is a terminal to coordinate motor terminal open detection current. .
  • Built-in overcurrent detection function, overheat detection function (output current OFF).
  • FAULT1 signal (active low) is output when any of motor terminal open, overcurrent or overheat is detected.  The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.
  • Built-in power on reset fun.
