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 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…

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 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 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 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…
