SI3402-A-GMR Overview
It is included in the Tape & Reel (TR) package.It is packaged in the way of 20-VQFN Exposed Pad.Controller (PD) is the type of PoE controller.The number of channels is growing strong/weak: 1.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.This electrical Po E controller operates at voltage 2.8V~57V.According to the base part number SI3402, its Po E controllers can be founded.Termination with a 20 termination involves terminating a transmission line with a power over ethernet controller of matching impedance.As you can see from the image, it is equipped with 20 pin count.Po E controller Power Management Circuits includes this component.A 20-pin design is used in it.For 2mA to perform fully, a supply current must be provided.A PoE power over ethernet controller with this maximum switching frequency has a 350kHz value.An electrical power over ethernet PoE controller like this can handle a maximum input voltage of 5.5V.This power over the ethernet controller can produce a maximum voltage of 0.68A.As a result of this power over ethernet controller's output voltage being 5V, this voltage is the output voltage.This power over ethernet devices requires a minimum input voltage of 4.5V to function.In terms of power output, this electrical PoE controller produces a maximum of 17W.
