Part Number: BOOSTXL-DRV8323RH
Tool/software: Code Composer Studio
Will BOOSTXL-DRV8323Rx EVM will it work on BOOSTXL-F28069M?
Where the guide (PDF) to use it, how it fits between them.
Thanks for posting on the MD forum!
Which code do you plan to use for spinning the motor? Instaspin FOC? Your own code?
On the surface yes they are compatible but we don't have 100% ready code to use for that MCU. The Instaspin code can be fairly easily adapted though.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Adam Sidelsky:
I like to focus on Instaspin Motion and sensored (no FOC) to run as a demo for my boss. I will be using GUI universal software to run this.
What difference I need to be aware of to upgrade code from 28069M that run on BOOSTXL-DRV8305 to BOOSTXL-DRV8323, I was wondering if any of you done this before?
What encoder PN should I buy?, from a quick read, it says ABI interface with 1000 step?
I have ordered the BOOSTXL-DRV8323 Eval board. I guess it also works on DRV8353 (100V) as well but there no BOOSTXL board, do you plan to make one?
Do you have an article or paper to cover the topic when Motor becomes a generator that raises up the bus voltage when jammed or stops rotation rapidly?
In reply to richard payne:
The C2000 team can help you with the MCU, I can send your post their way once you're ready.
I don't have an encoder recommendation unfortunately but maybe you can use the same one that the C2000 team may have used with their code.
The DRV8353R EVM uses C2000 and Instaspin but it's not technically a BOOSTXL yet has the same features and similar pinout.
Our DRV8343-Q1 discusses this in the section titled "10.1 Power Supply Consideration in Generator Mode" in the datasheet here: http://www.ti.com/lit/ds/symlink/drv8343-q1.pdf?ts=1590165106392
Thank for quick reply. I found the suitable encoder.
I have read section 10.1 of DRV8343 but this is battery setup.
I have a 3 phase generator attached to the motor with rectifier circuit. I wondered how to manage the motor in the generator mode.
I'm more concerned with braking or jamming stops which may lead to back voltage to the power bus. Is there a way to limit this via H Bridge?
Would you by any chance have bare board DRV8323 so I can fit in DRV8353 and higher voltage MOSFET?
We don't have a way to prevent this phenomenon but if sudden stops are needed then you can implement external circuitry such as a braking resistor circuit or battery cut-off.
I don't have any bare boards unfortunately.
