DRV8833 common ground?

I have only a single supply and need to run the motor controller and the processor (via a 5V ldo regulator). In doing so, I’ll have to tie the signal ground to the motor ground. Is that acceptable?

Thanks,
Jim.

Hello, Jim.

You should connect the DRV8833 dual motor driver as shown in the minimal wiring diagram found on the driver’s product page. The grounds between the motor power and signal power should be tied together. Since you are powering both from the same power source, you would already be making the ground connection between the two devices.
