LTC4258CGW#PBF Overview
It is embedded in the Tube package.36-BSOP (0.295, 7.50mm Width) is how it's packaged.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.Strong/weak channels are increasing: 4.In order to maintain reliability, PoE operates at a temperature of 0°C~70°C.This electrical Po E controller operates at voltage 47V~57V.The base part number LTC4258 determines the Po E controllers.An 36 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.During normal operation, this electrical ethernet over power controller will produce 15.4W Watts of power.With 36 pins, it is equipped.Taking into account the supply current, 2mA is the value.This Po E controller is included in Power Management Circuits.The peak reflow temperature (Cel) of this electrical ethernet power controller is 260.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 4V value is reached.As the current required for its operation (Vsup) reaches 3V, the PoE ethernet controller is operating.
