DRV8872-Q1: Dual Independent PWM Outputs

Hi Jessica,

For this device you can't control them independently:

Can you let me know the load profile as well as the operating voltage and I can suggest a new part.

Thank you for the quick reply.  

I am actually using them as general purpose PWM outputs:

- Operating voltage: 7V to 35V
- Output current < 10mA
- Frequency up to 100kHz
- 0% to 100% duty cycle
- Dual channel (independent) preferred for space considerations
- Automotive + functional safety

It looks like the DRV8876-Q1 might be a good option since it looks like it is possible to run the two bridges independently.  Is there another part you would recommend?  

Hi Jessica,

DRV8876-Q1 is an option like you said:

100 kHz is relatively high switching frequency, so there aren't that many options left that are also HW and integrated. Is this a hard requirement?

What application is this for?

It's a general purpose output which may be used in a range of applications.  If there are lower cost / simpler options we could rethink that requirement.  

Hi Jessica,

I have asked the marketing team for some input. I will update you Monday.

Is there a reason you would recommended the DRV8242-Q1 over the DRV8876-Q1?  It's a little more expensive, and I don't need the higher current output for my application.

Hi Jessica,

It is a newer part, and it is what we recommend for newer designs. There are also a lot more diagnostics and features in the DRV8242 if needed.
