PM8803 Overview
It is embedded in the Tray package.Packaged in the manner of 20-TSSOP (0.173, 4.40mm Width) Exposed Pad.PoE controllers of this type are called Controller (PD), DC/DC.Strong/weak channels are increasing: 1.PoE operates with the operating temperature of -40°C~85°C to ensure its reliability.An associated part can be established based on the base part number PM8803.There are 20 terminations, which are the practice of ending a transmission line with a power over ethernet controller that matches the characteristic impedance of the line.It has a maximum power of 25.5W Watts.In addition, it is equipped with a 20 pin count.Po E controller Switching Regulator or Controllers includes this component.There is a 260 thermal peak of this electrical ethernet power controller (Cel).This mount is positioned in the way of the Surface Mount axis.It is important to note that the operating supply voltage of this PoE controller is 3.6V.An power over ethernet devices of this type requires a minimal input voltage of 32.5V.
