Part Number: DRV8872
Other Parts Discussed in Thread: DRV8871, DRV8870,

Hi, Team

What's the frequency of integrated charge pump of DRV8872-Q1?

Customer has concern on EMC.

Is this part equipped with spread spectrum or other technology for better EMC performance?

Is there any support document available?

Thank you.

Hi Alvin,

We will have to investigate this the frequency of the internal charge pump. Expect an answer by Thursday.

Yes, the DRV8870, DRV8871, DRV8872, and DRV8872-Q1 have spread spectrum integrated.

What type of support document are you looking for?

Hi, Rick

If we have any report on EMC test, that would be helpful.

Hi Alvin,

We do not appear to have this data. I will close the thread for now.
