DRV8873-Q1: The VCP pin adopts the form of 1uf+220nf capacitor in parallel, is there potential risk

Bao Songhao

Part Number: DRV8873-Q1

Tool/software:

Hello, I see pdf recommended that VCP pin add 1uf capacitor, but in the process of debugging found that RE interference is too large, so the VCP pin adopts the form of 1uf+220nf capacitor in parallel, the chip can work normally, and the interference is also small, I wonder if this is feasible? Whether there are potential risks

Hi Bao,

While we do not expect there to be any change to the device functionality with the VCP capacitance configuration used. We cannot guarantee that the device will work as outlined in the datasheet if the datasheet recommended values are not followed.

Regards,

Joshua
