Part Number:DRV8825
In the datasheet it states "Connect a 0.1-μF 16-V ceramic capacitor and a 1-MΩ resistor to VM" yet in all of the reference designs provided this resistor is not there. What is the reason for the 1-MΩ and why isn't it even an option for any of the designs?
Along the same lines I see some designs using a 0.1uF cap across the sense resistors but in most cases it is not shown in the schematic.
