DRV8801 VPROPI bandwidth

Jonathan Jank

What is the Bandwidth of the VPROPI output signal?? I'm trying to understand how much it will rolloff my current sense signal.

For reference, the external RC that you show in the datasheet has a 1.5kHz BW. (100k, 1000pF)

thanks,

Hi Jonathan,

We will check and get back to you. This may take a few days.

We are still needing this information and also need to know what the offset error typically will be during a zero current situation??

thanks

Hi Jonathan,

Thanks for reminding us. The designer is back in the office. I hope to have the information soon.

Hi Jonathan,

The bandwidth of the VPROP is approximately 1MHz. I will have to check further with the designer on the offset error.
