Part Number: DRV8849EVM Hello
I'm testing the DRV8849EVM to drive 2 stepper motors at full scale current 1.5A, provoking an fault on driver, not present if I use less current.
Afther mesuring temperature on chip, its over 100º before failing, I assume…

Part Number: DRV8849EVM Tool/software: Hello,
I am trying to drive the DRV8849EVM with the DRV88XEVM-GUI. I am getting an 8dot3 error on my windows 11 system, but when I follow the steps to enable this file convention I get an error within the command…
Hi Annie,
Yes, an external microcontroller is required to send the step pulse. I would recommend looking at our DRV8849EVM which has the firmware files available for evaluation purposes.

Hi William,
For most applications, using inductors/ferrites are not necessary.
The bypass capacitors values are in the external component section of the data sheet:
200 uF of bulk capacitance should be added to VM.
An example of the bulk…
Hi Carson,
Thanks for posting in this forum.
Carson Spoo said: I previously worked with the TI DRV8834, which had internal charge pumping and didn't require any charge pumping peripherals to work.
The DRV8834 had a higher frequency charge pump and…
