LTC4257CDD-1#PBF Overview

The package Tube includes it as part of PoE controller.It is the way it is packaged that makes it 8-WFDFN Exposed Pad.In this application, it is an PoE controller that is of the Controller (PD) type.Currently, there are a number of channels that are strong or weak: 1.For the sake of ensuring the reliability of the Po E controller, it functions at a temperature of 0°C~70°C.In this electrical Po E controller, the voltage of the supply is 57V Max.There is a possibility of determining its Po E controllers by referring to the base part number LTC4257.A 8 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.As far as the maximum power of this electrical ethernet over power controller is concerned, it is 12.95W Watts.As you can see from the image, it is equipped with 8 pin count.There is a current of supply amounting to 3mA.A Po E controller like this is included in Power Management Circuits.During reflowing of the electrical ethernet power controller, the peak temperature (Cel) reaches 260 °C.The maximum current that can be provided for its operation (Isup) is reached at 3mA.In addition, it is characterized by the letter REQUIRES A NEGATIVE SUPPLY OF 48V.
