SI3453A-B02-GMR Overview
Embedded in the Tape & Reel (TR) package, it is used by many applications.In this case, it is packaged in the same way as 40-VFQFN Exposed Pad.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.There is a strong/weak growth in the number of channels: 4.For a reliable operation, -40°C~85°C is the PoE operating temperature.Electricity is supplied to this Po E controller by voltage 45V~57V.Base part numbers SI3453 can be used to establish Po E controllers.In a 40 termination, a transmission line is terminated with an impedance-matched power over ethernet controller.40 pins are equipped with it.A 40-pin design is used in it.There should be a difference between the supply voltage and 3.3V in the supply voltage.To function properly, 4mA needs a supply current.A PoE controller of this kind can produce a maximum power of 40W.
