DRV2700: Controller chip for piezo motor

Hi, Sebastian,

Welcome to E2E and thank you for your interest in our products.

Based on the operating voltage, the DRV2700 and the DRV8662 would be the best options. However, if you are interested in more of our Piezo drivers, you may take a look at our Piezo drivers folder:

Hi Luis.

Thanks for your reply. I took a look at the datasheets. I am not sure, if this is what I am looking for.

Is microstepping possible with these chips? I want to drive a scanning stage. Are these chips suitable for that? I found no documentation of any driving commands,.... Does it require an additional controller?

Best regards,

Sebastian

I´m sorry, it looks like my initial post does not contain all the information I thougt I wrote down......

I am looking for a chip that uses position, velocity, acceleration, some configuration parameters as its input, and then generates the driving signals, such as motor current, calculates the velocity ramp and maybe has an input for an encoder, to use it in a closed loop system.
Hopefully my requirements are more precise and complete now :)

Hello Luis.

Thanks a lot for your answer!!

Sebastian
