LTC4274AIUHF-1#TRPBF Overview
It is included in the Tape & Reel (TR) package.In this case, it is packaged in the same way as 38-WFQFN Exposed Pad.PoE controllers of this type are called Controller (PSE).Strong/weak channels are increasing: 1.As a precaution, the operating temperature of this Po E controller is kept at -40°C~85°C in order to maintain its reliability.The supply voltage of this electrical Po E controller is 45V~57V.The base part number LTC4274 determines the Po E controllers.An 38 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.Power can be reached by this electrical ethernet over power controller at a maximum of 38.7W Watts.In addition, it is equipped with a 38 pin count.In this case, 2.4mA is the supply current.Power Management Circuits includes this Po E controller in its package.A voltage higher than 3.3V should be applied to the supply.During its operation, Isup reaches 5mA, the maximum current.4.3V is reached when the maximum current (Vsup) supplied for its operation reaches.When the minimal current (Vsup) required for its operation reaches 3V, then it is ready to operate.It is powered by 3.354V batteries.
