DRV8873-Q1: Frequencies to Generate for EMI Test

Part Number: DRV8873-Q1
Other Parts Discussed in Thread: DRV8889-Q1,

Hello,

In preparation for an EMI test, I'd like to know about frequencies the DRV8873S-Q1 can generate. I guess the device has internal oscillators. Could you provide me with their frequencies?

Best regards,

Hi Yokota-san,

Looks like your post was accidently duplicated. I will close this one, and reply here: https://e2e.ti.com/support/motor-drivers/f/38/t/947501.

Mike-san,

No, it's not a mistake. I ask about two devices - DRV8873S-Q1 and DRV8889-Q1. I got an answer on the DRV8889-Q1, but not yet on the DRV8873S-Q1.

Best regards,

Yokota-san,

Ah, my mistake!

DRV8873-Q1 has a 400KHz chargepump, and 10MHz internal oscillator for the digital circuits.
