DRV8353R: Help needed for Servo motor controller scheme

Hi Basit,

Thanks for reaching out! The DRV8353R should be able to support this motor. If you plan on operating the device at 24V (which is the voltage rating of this motor) then I would recommend looking into the lower voltage DRV8323R which has a 65V abs max (still plenty of margin for 24V applications). While the DRV8353R could work, it is more targeting 48V applications. 

I am going to reassign this thread to the MCU team to discuss a suitable MCU for your application.

Thanks. Actually I was thinking how to use the RS485 encoder here. The picture I have on mind is using a dedicated servo controller with this smart gate driver and a master controller that will be controlling the 4 dedicated servo controller (servo motors) with one master controller.

Hi, Basit

Do you need any help from microcontroller side?

Yes. I would like to ask if DRV8323R will be directly connected to a microcontroller or there is a servo driver (SPI based) which is interfaced with DRV8323R directly. As I will be controlling 4 of these motors through one microcontroller.

You may refer to the links below for RS485 based encoder

Thanks both the responses were very helpful. Last thing, will MCF8329A is suitable for my application with respect to the motor parameters.
