DRV8889-Q1: how long does it take for the current to stabilize?

Part Number: DRV8889-Q1

Hi,

When the STEP signal stops (the motor stops), how long does it take for the current to stabilize?

Thanks & best regards,

  • Hey David,

    The exact time will depend on your motor model, load, speed, and operating voltage.  I recommend probing a motor on a scope and observing it yourself.  

    The output slew rate (t_SR) on this device is selectable from 10V/us to 105V/us, this will change how quickly the output turns on or off.  

    Best,

    Jacob
