1) Our team wants to make sure we are using the latest RT schematic - Is 2016 the latest? If not, where is the latest.
2) The RT-2016 schematic, pg 9, Current Monitor circuit has a 60mOhm resistor, but the BoM lists part WSL25126L000FEA which is 6mOhm. It seems the 6mOhm part is needed to dissipate less than the resistor's rating of 1W. What was used a 6mOhm or a 60mOhm resistor?
3) Based on the LTC2990 datasheet, (also on a page 9), it isn't clear if the undervoltage threshold applies only to V1 or if it applies to V3 as well. A search of 'UV' in the document doesn't explicitly reveal a link. It may be important because the IO voltage based on the jumper defaults is 3.3V and VCC for the LTC2990 is also set to 3.3V. What is your experience with this and how this chip works? Is it a non-issue? Does the FPGA configure the LTC2990 each time and so we can ignore whether a reset takes place or not for it?
Hello, I have a few questions-
