DRV8353RS-EVM: JP1, JP2, JP3 (GND, 3V3, 5V0) - of Launchxl-F280025C, should they be kept open when connected with DRV8353RS-EVM ?

Hi Anil,

Let me and try and get a better understanding what you're trying to do. 

Are you trying to use the step up converter option that involves JP9?

Hi Yara,

Hi Anil,

So from my understanding you are just wanting to know the hardware configurations of the Launchxl-F280025C with the DRV8353RS-EVM?

please refer to the following guide (page 11 in your case)

https://www.ti.com/lit/ug/spruj26/spruj26.pdf?ts=1699499556611&ref_url=https%253A%252F%252Fwww.google.com%252F

Let me know if this answers your question.

Hi Yara,

Please see the text in my earlier post >>>>> Present configuration suggested in user guide will make output of 3.3V regulators on F280025C board and Drv8353 board short. 

I have done configuration as per page 11 in user guide.  With that I see 3.3V  of Launchxl-F280025C and 3.3V of DRV8353RS-EVM getting shorted.  My understanding is this is not OK.  Hope you understand the issue now.  Please let me know how to handle this..

Anil

Hi Anil,

From my understanding the Launchxl-F280025C and the DRV8353RS-EVM have been tested using the configuration found in the manual. There should not be an issue such as a board short if you follow the configuration. From the manual it looks like JP9 is kept OPEN and JP1,2,3 are short.

Still, I will confirm with my team to make sure this is the case. I will give an update early next week.
