Hi,

I want to use the DRV8353 on my next Motor control design.

What Low Pass Filter (values of R and C) do you recommend for a 20kHz commutation frequency application please?

Best regards,

David

Hey David,

We suggest having a cutoff frequency that is 30-50 times higher than the PWM frequency you plan to send. The exact value can be adjusted as you test if you have the footprint in your layout.

Best,

Akshay
