how is MPS (maintain power signature) implemented in POE designs?
the spec says to have a 10mA load at a certain interval - which how it is done with Class 0 or 1
I do not see how its being done on any designs or sample boards I have seen (like the TPS 2375 eval board)
but these boards work even with no load connected
how does a class 0 POE device support a 10ma MPS?...if it draws 4mA only
