SI3452-B02-GM Product Details
SI3452-B02-GM Overview
The package Tray includes it as part of PoE controller.It is packaged in a way that resembles 40-VFQFN Exposed Pad.In this application, it is an PoE controller that is of the Controller (PSE) type.Channel growth is strong or weak: 4.For the sake of ensuring the reliability of the Po E controller, it functions at a temperature of -40°C~85°C.Electrical Po E controller 45V~57V has a 45V~57V supply voltage.Base part numbers SI3452 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.In addition, it is equipped with a 40 pin count.There is a Po E controller named Power Management Circuits that includes this Po E controller.There is a 40 pin design on this board.There should be more voltage supplied than 3.3V.When Vsup reaches 3.6V, the maximum current is supplied for its operation.For 3.7mA to perform fully, a supply current must be provided.When the minimal current (Vsup) required for its operation reaches 3V, then it is ready to operate.This electrical PoE controller has a maximum output power of 40W.
