Re: Banebots RS-775 Case Short

Eric,
All we are really worried about is the voltage change at the power input to the Crio. There does not need to be a trip in the PD. It is like adding huge amounts of ripple in linear power supply. All that has to happen is for the power at the Crio to upset the internal power sense and the Crio reboots. Considering that switching PWM is a significant component in the current in this line, the internal regulators of the Crio likely give up pretty easy. I suppose it is also possible that the 24 regulator gets fooled into restarting but I really doubt it. Added to the switching, you have sometimes huge amounts of RF generated by the brushes and switching, particularly in the Jag.
