PM8803 [STMicroelectronics]

PM8803 Overview

The package Tray includes it as part of PoE controller.It is the way it is packaged that makes it 20-TSSOP (0.173, 4.40mm Width) Exposed Pad.In this application, it is an PoE controller that is of the Controller (PD), DC/DC 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 -40°C~85°C.There is a possibility of determining its Po E controllers by referring to the base part number PM8803.A 20 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 25.5W Watts.As you can see from the image, it is equipped with 20 pin count.A Po E controller like this is included in Switching Regulator or Controllers.During reflowing of the electrical ethernet power controller, the peak temperature (Cel) reaches 260 °C.This PoE ethernet controller is mounted in such a way that it faces Surface Mount.This PoE controller requires a supply voltage of 3.6V to function properly.In order for this power over ethernet devices to function properly, it requires a minimal input voltage of 32.5V.
