MAX5940DESA+ Overview
It is included in the Tube package.It is packaged in the way of 8-SOIC (0.154, 3.90mm Width).As far as this application is concerned, it is a Controller (PD) type PoE controller that is being used.A strong/weak channel growth trend has been observed: 1.Ensure the reliability of the PoE by operating it at -40°C~85°C.In order to operate this electrical Po E controller, it requires a voltage of 39.9V~67V as a supply voltage.It is possible to identify its Po E controllers based on its base part number MAX5940.8 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.There is a maximum power of 12.95W Watts in this electrical ethernet over power controller.Count of 8 pins is included.Current supply equals 400μA.There is a Po E controller like this in Power Management Circuits.There is a certain temperature that this electrical ethernet power controller reaches during reflow (Cel) of 260.There should be a greater voltage at the supply than at 48V.The maximum current (Vsup) that can be supplied for the operation of the ethernet power controller reaches the point 67V.A 48V power supply is used to operate it.
