SI3452B-B01-GM Overview
PoE controller is part of the Tube package, which is included in the download.It is the way it is packaged that makes it 40-VFQFN Exposed Pad.PoE controller is a Controller (PSE) type electronic part.There is an increase in the number of channels strong/weak as follows: 4.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.This electrical Po E controller operates at voltage 45V~57V.Base part numbers SI3452 can be used to establish Po E controllers.In a 40 termination, the transmission line is terminated with a power over ethernet controller that matches its characteristic impedance.There is a pin count of 40 on this ethernet over power controller.There is a 40 pin design on this board.It is necessary to have a greater voltage than 3.3V in the supply.During its operation, maximum current (Vsup) of 3.6V can be supplied.Surface Mount is the direction it is mounted.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.
