SI3453C-B01-GM Overview

The package Tube includes it as part of PoE controller.In other words, 40-VFQFN Exposed Pad refers to the way in which it is packaged.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.It has been reported that the number of channels is growing strongly/weakly: 4.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.This electrical Po E controller operates at voltage 45V~57V.Using the base part number of a part SI3453, it is possible to determine its Po E controllers.An 40 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.There is a pin count of 40 on this ethernet over power controller.A 40-pin design is used in it.Ideally, the supply voltage should be greater than the 3.3V value.As you can see, it is mounted in Surface Mount-direction.For 4mA to fully function, the supply current must be provided.
