we got some question regarding the Classifcation Load Current of LTC4278; could you kindly help on it; please?
As shown in figure 1; if the PSE input port voltage is between 12.5V to On; the Classifcation Load Current will constantly be there?
In our test shown in Figure 3; we found when port voltage <=33V; 40+ mA current into LTC4278; which cause the chip temp rising to 85C @ 25C ambient temp.
If so; any method to relieve this issue? Many thanks!
