SI3452B-B02-GM Overview


As part of the Tube package, PoE controller is embedded.In this case, it is packaged in the same way as 40-VFQFN Exposed Pad.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.There is a strong/weak growth in the number of channels: 4.For the sake of ensuring the reliability of the Po E controller, it functions at a temperature of -40°C~85°C.There is a voltage of 45V~57V that is used for the supply voltage of this electrical Po E controller.An associated part can be established based on the base part number SI3452.An 40 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.With 40 pins, it is equipped.As Po E controller of Power Management Circuits, this Po E controller is included.The 40 pins are designed into it.It is necessary to have a greater voltage than 3.3V in the supply.As soon as the maximum current (Vsup) is supplied for its operation, the 3.6V value is reached.In order for 3.7mA to play its full role, it needs a supply current to be delivered to it.Its minimal current (Vsup) reaches 3V.A PoE controller of this kind can produce a maximum power of 40W.
