A basic circuit protection measure would be protection from inductive spikes. Using the INA219 in a motor current measurement application, possibly using the DRV8871 as the motor driver, configured with protection would be an excellent example showcasing both parts and answering a real world problem with them.

FYI... figure 1 has been updated with the feedback resistor values in the correct place. Rf=249K, R=1.00K, A= 250.

Hi Rookie,

Yes, You are correct the values have been swapped... Rf=249, R=1.00K. Nice catch. I'll have the figure fixed.

You sure those gain setting resistors are labeled correctly?
