The package Tape & Reel (TR) includes it as part of PoE controller.It is the way it is packaged that makes it 56-VFQFN Exposed Pad.PoE controller type Controller (PSE).Channel number is growing strong/weak: 8.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~125°C.There is a voltage of 3V~3.6V that is used for the supply voltage of this electrical Po E controller.The base part number TPS23881 determines the Po E controllers.In a 56 termination, a transmission line is terminated with an impedance-matched power over ethernet controller.This electrical ethernet over power controller has a maximum power of 127W Watts, which is the maximum power it can deliver.6mA is the amount of supply current that is available.There should be a difference between the supply voltage and 54V in the supply voltage.57V is reached when the maximum current (Vsup) supplied for its operation reaches.As soon as it reaches 44V, it receives its minimal supply current (Vsup).There is also a ALSO REQUIRE 3V TO 3.6V SUPPLY VOLTAGE characteristic to it.
