DRV8834: Which chip can replace the TMC2226?

Hey Tony,

I recommend the DRV8452 or DRV8461.  These have a similar package to the TMC2226 and better performance specs. A smaller more budget-friendly option is the DRV8425. 

Here are all our stepper drivers filtered for >29V and >=2A full-scale RMS current:  https://www.ti.com/motor-drivers/stepper-driver/products.html#3305=2%3B10&2716max=34%3B70&
