LTC4290BIUJ#TRPBF Overview
PoE controller is part of the Tape & Reel (TR) package, which is included in the download.Packaged in the manner of 40-WFQFN Exposed Pad.An PoE controller of this type is Controller (PSE).Currently, there are a number of channels that are strong or weak: 8.PoE operates with the operating temperature of -40°C~85°C to ensure its reliability.In order to operate this electrical Po E controller, it requires a voltage of 3V~3.6V as a supply voltage.Using the base part number of a part LTC4290, it is possible to determine its Po E controllers.In a 40 termination, a transmission line is terminated with an impedance-matched power over ethernet controller.During normal operation, this electrical ethernet over power controller will produce 25.5W Watts of power.In addition, it comes with a 40 pin count.It amounts to 10mA that the supply current is flowing.There is a Po E controller like this in Power Management Circuits.15mA reaches its maximum current (Isup).Powered by a 3.354V power supply, it runs on batteries.ALSO REQUIRED VDD OF 3V TO 3.6V is also an important characteristic of it.
