SI3452B-B02-GMR Overview
The package Tape & Reel (TR) includes it as part of PoE controller.Packaged in the manner of 40-VFQFN Exposed Pad.I would like to inform you that this PoE controller is of the Controller (PSE) type.It has been reported that the number of channels is growing strongly/weakly: 4.Ensure the reliability of the PoE by operating it at -40°C~85°C.There is a voltage of 45V~57V that is used for the supply voltage of this electrical Po E controller.The base part number SI3452 determines the 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.As you can see from the image, it is equipped with 40 pin count.The Po E controller in question is Po E controller of Power Management Circuits.The 40 pins are designed into it.Ideally, the supply voltage should be greater than the 3.3V value.3.6V is reached when the maximum current (Vsup) supplied for its operation reaches.As a requirement for 3.7mA to function properly, it must be supplied with a current.3V is reached once it receives the minimal current (Vsup) it requires to operate.In this electrical PoE controller, 40W is the maximum output power that it can deliver.
