Part Number: DRV8376
Other Parts Discussed in Thread: DRV8378, DRV8374, MSPM0G3507, DRV8316, DRV8311, DRV8317

Tool/software:

Will new members of DRV837x-Family (DRV8374 and DRV8378) have the same structure of SPI registers like this in DRV8376?

Hi Zbyno,

The SPI read and write format looks to be the same as DRV8376.

Thank you,

Joseph

Hi Joseph

thanks.

Does the application for DRV8379 exist for the MCU Family MSPM0G350x?

Hi Zbyno,

Could explain your question further? Are you asking about EVM compatibility?

Thank you,

Joseph

Hi Joseph

I have asked if the FOC application was also written for DRV8376 (DRV8374).

Hi Zbyno,
I changed the BU to MSP HSM since the MSPM0G family falls into the MSP high speed and memory devices. They will let you know if there are plans to use it for the DRV8379. In the case the answer is no, I recommend to use the current code that we have for the and modify it so it fits the DRV8379.

Best Regards,

Diego Abad

I am not familiar with the DRV8379 driver. (I couldn't find it). I want to write SW for the estimated drivers DRV8374 or DRV8378.

Hi Zbyno,

The DRV driver examples we achieved for MSPM0G3507 in SDK could be found below. Currently the DRV8376 driver example is not included in our SDK, but you could refer these examples for DRV driving and FOC achievement.

Best Regards,

Pengfei

Hi Pengfei,

I knew it. I have hoped for the unpublished news..

Hi Zbyno,

The FOC example based on DRV8376 is not planned to develop.

If you do need this example for your project, could you please contact the TI sales team and provide your requirement and project business information, so that we could evaluate internally to see how to support your case.

Best Regards,

Pengfei

Hi Joseph,

I would like to know more about all members of the DRV83xx family (drivers with internal power MOSFETs). I have still only tested it with my design with DRV8316, and it was a separation of the power outputs from the IC (OutA, etc) to the motor inputs (U, V, W ) with the power inductor

like 2743021446 from Fair-Rite.

Hi Zbyno,

You can view the product pages for our integrated MOSFET (DRV83xx) linked below. These will have information regarding datasheets, capabilities of the parts, power ratings, that you may be looking for.

Thank you,

Thanks Joseph,

I knew these ICs. My question was: if this coil (ferrit) on the output pin could make the EMC better, and

If it will be necessary to add the Schottky diode (the anode on the ground) between the IC's output and the ferrite.

Hi Zbyno,

I understand your question,

I have used ferrites on output on some of our EVM's before with no issues. This is somewhat system dependent however.

It may improve EMC but testing would need to be done with your application to confirm.

I don't think the Schottky would be necessary.

My question is, have you seen concerning amounts of EMI in your testing of DRV8316 that is prompting you to use these Ferrites on outputs? I don't see how these would be necessary in the majority of applications.

Thanks,

Joseph
