SI3452-B02-GMR Overview
As part of Tape & Reel (TR), PoE controller is embedded.40-VFQFN Exposed Pad is how it's packaged.An PoE controller of this type is Controller (PSE).Channel number is growing strong/weak: 4.For a reliable operation, -40°C~85°C is the PoE operating temperature.The supply voltage of this electrical Po E controller is 45V~57V.It is possible to find the Po E controllers of the base part number by using the base part number SI3452.A 40 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.As you can see from the image, it is equipped with 40 pin count.As Po E controller of Power Management Circuits, this Po E controller is included.It is designed with 40 pins.There should be a greater voltage at the supply than at 3.3V.The maximum current (Vsup) that can be supplied for the operation of the ethernet power controller reaches the point 3.6V.The supply current of 3.7mA needs to be provided to fully play its function.Upon reaching 3V, the minimal current (Vsup) required for its operation is reached.40W is the maximum power this electrical PoE controller can produce.
