MAX5971AETI+ Overview
PoE controller is part of the Tube package, which is included in the download.28-WFQFN Exposed Pad is how it's packaged.PoE controllers of this type are called Controller (PSE).Channel growth is strong or weak: 1.For the sake of ensuring the reliability of the Po E controller, it functions at a temperature of -40°C~85°C.In order to operate this electrical Po E controller, it requires a voltage of 32V~60V as a supply voltage.An associated part can be established based on the base part number MAX5971.A 28 termination corresponds to the practice of terminating a transmission line with an impedance-matching power over ethernet controller.As far as the maximum power of this electrical ethernet over power controller is concerned, it is 40W Watts.Count of 28 pins is included.A Po E controller like this is included in Power Management Circuits.28 pins are used in the design of this board.Ideally, the supply voltage should be greater than the 54V value.It reaches 4mA when it receives the maximal current (Isup).During its operation, maximum current (Vsup) of 60V can be supplied.This PoE ethernet controller is mounted in such a way that it faces Surface Mount.The supply current of 2.5mA needs to be provided to fully play its function.Upon reaching 32V, the minimal current (Vsup) required for its operation is reached.32/60V power supplies are used to power it.
