SI3402-B-GMR Overview
There is an embedded version of it in the Tape & Reel (TR) package.It is packaged in the way of 20-VQFN Exposed Pad.Controller (PD), DC/DC is the type of PoE controller.A strong/weak channel growth trend has been observed: 1.For a reliable operation, -40°C~85°C is the PoE operating temperature.Electrical Po E controller 2.8V~57V has a 2.8V~57V supply voltage.A 20 termination involves terminating a transmission line with a power over ethernet controller whose characteristic impedance matches the line's.In the case of this electrical ethernet power controller, the peak reflow temperature (Cel) is 260 degrees Celsius.To work properly, 2mA needs to receive supply current.A 350kHz frequency is used for the operation of this electrical PoE ethernet controller.Using this power over the ethernet controller, you can achieve a maximum voltage output of 0.68A.
