SI3452A-B02-GM Overview
PoE controller is part of the Tube package, which is included in the download.The packaging is in 40-VFQFN Exposed Pad's style.I would like to inform you that this PoE controller is of the Controller (PSE) type.There is an increase in the number of channels strong/weak as follows: 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.A base part number SI3452 can be used to identify its Po E controllers according to that number.A 40 termination corresponds to the practice of terminating a transmission line with an impedance-matching power over ethernet controller.In addition, it is equipped with a 40 pin count.A Po E controller like this is included in Power Management Circuits.There is a 40 pin design on this board.There should be a greater voltage at the supply than at 3.3V.It reaches 3.6V when the maximal current (Vsup) supplied to it for its operation reaches its maximum value.The supply current of 3.7mA needs to be provided to fully play its function.3V is reached once it receives the minimal current (Vsup) it requires to operate.It is estimated that the maximum output power of this electrical PoE controller is 40W.
