SI3452D-B02-GM Overview
It is embedded in the Tray package.It is the way it is packaged that makes it 40-VFQFN Exposed Pad.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.Currently, there are a number of channels that are strong or weak: 4.Keeping its operating temperature at -40°C~85°C ensures PoE reliability.This electrical Po E controller receives its supply voltage from 45V~57V.An associated part can be established based on the base part number SI3452.40 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.The ethernet over power controller has 40 pins.This Po E controller is included in Power Management Circuits.As you can see, it is designed with 40 pins.The supply voltage should be greater than 3.3V.During its operation, maximum current (Vsup) of 3.6V can be supplied.In order for 3.7mA to perform its proper functions, it needs to have a current supply that is adequate.Upon reaching 3V, the minimal current (Vsup) required for its operation is reached.A PoE controller of this kind can produce a maximum power of 40W.
