DRV8350: Continuous Sinusoidal 180° Commutation using DRV8350

Part Number: DRV8350
Other Parts Discussed in Thread: DRV8353, MOTORWARE

Hi all

Would you mind if we ask DRV8350?

We assume that it is possible to configure Continuous Sinusoidal 180° Commutation using DRV8350.
In this case, 6-PWM IF and external CPU require for these.
We would like to ask gate drive timing for Continuous Sinusoidal 180° Commutation.
Could you show us the gate wave form as the reference?

Kind regards,

Hirotaka-San,

Unfortunately we do not have this code available. We have only trapezoidal and FOC available for our drivers.

Vignesh,

Sorry I missed your reply.

An example of Trapezoidal code can be found in the firmware here: http://www.ti.com/lit/zip/slvc755

An example of FOC code can be found in the firmware here: http://www.ti.com/tool/DRV8353RH-EVM

The FOC code requires installation of Motorware and some files to be exchanged so it's a bit more complex of setup.

Regards,

-Adam
