Hi James,
I am assuming that you wish to drive a 3A full scale current rated motor using the DRV8823. If that is the case, then the DRV8823 will not be able to drive a 3A motor since the DRV8823 has up to a 1.5 A motor winding current rating.
I can…
Hi Yaita
I confirmed you finding. I think this is because of some bugs during the command receiving process of the MCU firmware from the USB simulated COMx. So there will be some time the MCU didn't outputs correct "speed info" to DRV8828. But everything…
Other Parts Discussed in Thread: DRV8828 Hi,
We are using TI DRV8828/29 evm for stepper motor control (datasheet attached, part number SST43D2100). I am trying to run this motor using TI GUI (CPG006_DRV88XX), but motor is not running smoothly and it…
Hi MarkUs,
Have you looked at the DRV8828, DRV8829, or DRV8842? These may be a better fit.
Unless specifically stated in the datasheet, it is not recommended to connect the outputs in parallel. Timing mis-matches can create events that look like…
Hi Raju,
I remembered the using of DRV8829EVM with GUI in the external index mode (with the help of the MCU on the EVM) was very smooth if you followed the EVM User's Guide step by step.
Note that DRV8828/29 don't have on-chip index mode.

Hello Duncan-san,
Thanks your support.
I understand DRV8802-Q1 is not recommended in this case.
Do you have plan DRV8828 in AEC-Q100 grade?
I ask customer possibility of DRV8801-Q1.
Regards,
Shinya Muramatsu.
Hi Gary,
Not completely sure what your are after, but have you looked at the DRV8828 and DRV8829. With these devices (2 required for stepper operation), the current is controlled by varying VREF with a DAC or setting a fixed VREF and varying the Ix…
Hi Yaita-san,
The PCB information can be found by searching for the DRV8829EVM. At this folder, http://www.ti.com/tool/drv8829evm , scroll down toward the bottom of the screen. The files are listed under Software. The file Board Files and Software:…
Hi Raju,
Please refer to
Application Report 1 -- High-Resolution Microstepping Driver with the DRV8828/29/40 ( LINK )
Application Report 2 -- High Resolution Microstepping Driver With the DRV88xx Series ( LINK )
These provide a basic understanding…
