SI3452D-B02-GMR Overview
The package Tape & Reel (TR) includes it as part of PoE controller.The packaging is in 40-VFQFN Exposed Pad's style.PoE controller type Controller (PSE).Channel growth is strong or weak: 4.For the sake of ensuring the reliability of the Po E controller, it functions at a temperature of -40°C~85°C.A 45V~57V voltage is used to supply power to 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.A 40-pin design is used in it.3.3V should be greater than the supply voltage.When Vsup reaches 3.6V, the maximum current is supplied for its operation.3.7mA requires a supply current to function correctly.When the minimal current (Vsup) required for its operation reaches 3V, then it is ready to operate.The maximal output power of this electrical PoE controller is 40W.
