Part Number: DRV8825 Other Parts Discussed in Thread: DRV8434 , Dear Team,
Our customer would like to estimate the thermal risk in their board.
As you know, Thermal information is in datasheet.
However, They don't know how to estimate the loss wattage…
Part Number: DRV8825 I'm using the DRV8825 driver and having trouble with (unloaded) stepper motors 'stalling' at some speeds.
In this application I need the motor to spin at at max of 1000 RPM. I'm using a quadrature encoder knob and small…
Part Number: DRV8825 I have a doubt for this IC, Its working good,but i connect my stepper with the kit the chip (DRV8825) starts heating up.
Please how to avoid this issue.
Part Number: DRV8825 Dear all,
Based on the datasheet DRV 8825, the theory of calculating of maximum current limit is Vref / (5x Rsense)
If my Vref = 1V, then theoretically, my limit current shall be 2Apeak. Can I assume that I should be…

I am using DRV8825PWP IC for driving the Nema-17 stepper Motor. The inputs provided are as follows,
Driver IC supply voltage -15V
Step input frequency…
Part Number: DRV8825 Hello,
I need the meaning of the distortion of the current with the driver DRV8825.
The simplified schematic of my board is as follow:
0670-00.pdf
When I start the motor I see that the current is distorted. In these point (current…
Part Number: DRV8825 Hello,
I am making a PCB and I want to include the DRV8825 to control step motors. In a previous iteration I used the DRV8825 module, but, now, I want to use only the chip. I would like to know if there is some firmware that should…
Part Number: DRV8825 Hi Team,
When driving a stepper motor with DRV8825, it does not output a normal square wave but instead produces a spike on the way the square wave drops as the following waveform shown:
The customer erases the software and powers…
Part Number: DRV8825 Hi,
I am using a DRV8825 in a project and having some issues with the DIR pin not actually changing direction when pulled high or low. I have a script that moves the motor, stops it, and changes direction to move again. When the…
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…
