SI3453A-B02-GM Overview
The package Tray includes it as part of PoE controller.In this case, it is packaged in the same way as 40-VFQFN Exposed Pad.PoE controllers of this type are called Controller (PSE).Currently, there are a number of channels that are strong or weak: 4.Ensure the reliability of the PoE by operating it at -40°C~85°C.The supply voltage of this electrical Po E controller is 45V~57V.A part number's Po E controllers of SI3453 can be determined by its base number.A 40 termination corresponds to the practice of terminating a transmission line with an impedance-matching power over ethernet controller.As you can see from the image, it is equipped with 40 pin count.There are 40 pins on the board that are designed for it.There should be a greater voltage at the supply than at 3.3V.For 4mA to fully function, the supply current must be provided.The maximal output power of this electrical PoE controller is 40W.
