DRV8332 PCB design for limited use of my project

SINGARAVELAN ARUMUGAM

Other Parts Discussed in Thread: DRV8332, DRV8312, CONTROLSUITE

sir,

I am doing M.Tech( power electronics and drives ) . For my project i choose DRV8332 to run BLDC motor in open loop system.

From the file

1) 0116.DRV8332EVM_RevA-Assembly

2) 1030.DRV8332EVM_RevA-Gerbers

3) 6330.DRV8332EVM_RevA-PDFs

The PCB in the above file is more complicated for me as a student

So please give me a solution to design PCB for my application mentioned below,

The PWM from microcontroller is given to DRV8332 and the three phase supply from DRV8332 is given to BLDC motor

(for open loop system)

same like this application diagram which i get it from DRV8332 datasheet

Please check out the following user guide for the DRV8312 (little brother to DRV8332).

http://www.ti.com/lit/ug/spmu276/spmu276.pdf

Figure 5 shows the basic functional block diagram on the hook-up you need back to a microprocessor for sensor-less control of a BLDC motor using voltage measurements of the back-EMF and a single bus current measurement on the low side using a single op amp as found on the DRV8332 kit.

You can also find an excellent video at the link below that describes this technique as used on the DRV8312.

Hi there,

I need Altium schematic and pcb library files of DRV8332 and DRV8312.

can you provide these files.

thnx.

Beytullah,

Unfortunately, these boards were not designed in Altium, so I am not able to provide this. We do have gerbers for the DRV8312 that are released in ControlSUITE.

Thank you Ryan,

I guess I need to do it by my self. If any one needs them, I can share them after a couple of days.

Beytullah,

Did you complete the Altium schematic symbol and layout footprint for this device? I'm about to create them from scratch and would prefer to double check yours. I'd be happy to help verify them for you and give you feedback.

Thanks,

David Orser

Hello David,

Did you end up with Altium files for the DRV8332?

If you have it and want to share, I would be happy to receive the files from you, as that could save me some work :-)

Unfortunately, the project related to this was cancelled so I never got very far in creating this footprint.

I have attached my footprint, as I left it several months ago. I expressly disclaim any fitness for use what-so-ever. Please be very careful and check the schematic and layout before using this footprint.

Great, thanks!

Will look at it in a little while.
