SI3452C-B02-GM Overview
It is included in the Tube package.It is packaged in the way of 40-VFQFN Exposed Pad.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.The number of channels is growing strong/weak: 4.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.In this electrical Po E controller, the voltage of the supply is 45V~57V.According to the base part number SI3452, its Po E controllers can be founded.A 40 termination involves terminating a transmission line with a power over ethernet controller whose characteristic impedance matches the line's.In addition, it is equipped with a 40 pin count.A Po E controller like this is included in Power Management Circuits.There are 40 pins on the board that are designed for it.It is necessary to have a greater voltage than 3.3V in the supply.When Vsup reaches 3.6V, the maximum current is supplied for its operation.For 3.7mA to fully function, the supply current must be provided.Upon reaching 3V, the minimal current (Vsup) required for its operation is reached.In this electrical PoE controller, 40W is the maximum output power that it can deliver.
