SI3452A-B01-GM Overview
Embedded in the Tube package, it is used by many applications.The packaging is in 40-VFQFN Exposed Pad's style.PoE controller is a Controller (PSE) type electronic part.There is a strong/weak growth in the number of channels: 4.In order to ensure its reliability, PoE operates at the operating temperature of -40°C~85°C.In this electrical Po E controller, the voltage of the supply is 45V~57V.Using the base part number of a part SI3452, it is possible to determine its Po E controllers.A 40 termination involves terminating a transmission line with a power over ethernet controller whose characteristic impedance matches the line's.The ethernet over power controller has 40 pins.This board is designed with 40 pins.It is recommended that the supply voltage be greater than 3.3V.As soon as the maximum current (Vsup) is supplied for its operation, the 3.6V value is reached.The mounting is in the Surface Mount-axis.3.7mA requires a supply current to function correctly.Its minimal current (Vsup) reaches 3V.
