Part Number: DRV8825 Hi Team,
Using the circuit diagram in the DRV8825 specification sheet, the motor can run with radiation causing the FCC to fail. With the other conditions unchanged, the FCC can be passed by unplugging the motor cable.
Would it be…
Part Number: DRV8825 Hi team,
With DRV8825 no load output, the output waveform looks like this. Is this normal?
Why is there a little pulse in the middle?
Thanks for your response and help.
Part Number: DRV8825 The problem is how one of two motors (one stepper driver on each) eventually stops. The fault pin goes down to zero volts.
So I am wondering why the fault pin is logic low to begin with. It is on a custom PCB (not a carrier or dev…
Part Number: DRV8825 Hi Team,
Based on the datasheet, when TI DRV8825 Vref (on pin 12 and pin 13) is set to 1.03V , the calculated chopping current is 2.06A .
(datasheet page 12)
* Note : our design R.sense = 100mΩ.
** Note : refer to attachment…
Part Number: DRV8825 Hi Team,
May I confirm with you for the below maximum current, is it referring to average or RMS current?
Thanks.

Customer are using our DRV8825 to drive a stepper motor which spec show as following. and the VM=24V, I_Chop=2A, 1/32microstep. When it works at 4000 step(1.8°)/s, the phase current show as following, and there is distinct noise…
Part Number: DRV8825 Hi, support team
My customer has the questions as follow:
We are designing a PCB to control three stepper motors and a spindle motor in a CNC mill/engraver.
Each stepper motor will be controlled with one T.I. DRV8825 IC.
We would…
