Hello~, We have used LM5072 as an IEEE802.3at PD module based on reference design of NI's LM5072-5V/25W (snvu110). Recently, our customer found that some POE+ switches are unable to deliver power more than 15.4W. We did not implement two-event detection circuitry (sheet 3). Thus, our customer think that is the root cause for type-2 classification failure. As we study the design of 2-event detection circuitry depicted in document snvu110, it seems that the 2-event detection result is connected to a LED only but not taken effect on LM5072. Can you confirm that 2-event detection do not take effect on LM5072 during type-2 classification? Thanks!
