SI3452A-B02-GMR Overview
The Tape & Reel (TR) package contains it.In other words, 40-VFQFN Exposed Pad refers to the way in which it is packaged.In this application, it is an PoE controller that is of the Controller (PSE) type.Channel growth is strong or weak: 4.PoE operates with the operating temperature of -40°C~85°C to ensure its reliability.This electrical Po E controller receives its supply voltage from 45V~57V.There is a possibility of determining its Po E controllers by referring to the base part number SI3452.40 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.As you can see from the image, it is equipped with 40 pin count.The Po E controller in question is Po E controller of Power Management Circuits.A 40-pin design is used in it.There should be a greater voltage at the supply than at 3.3V.3.6V is reached when the maximum current (Vsup) supplied for its operation reaches.3.7mA requires a supply current to function correctly.During the operation of the unit, it will require a minimal amount of current (Vsup) of 3V to operate.In terms of power output, this electrical PoE controller produces a maximum of 40W.
