SI3402-B-GM Overview
The package Tray includes it as part of PoE controller.20-VQFN Exposed Pad is how it's packaged.PoE controller type Controller (PD), DC/DC.It has been reported that the number of channels is growing strongly/weakly: 1.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.In this electrical Po E controller, the voltage of the supply is 2.8V~57V.A 20 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.There is a 260 thermal peak of this electrical ethernet power controller (Cel).In order for 2mA to play its full role, it needs a supply current to be delivered to it.In this electrical PoE ethernet controller, the frequency is 350kHz.It is important to note that this power over the ethernet controller has a maximum voltage output of 0.68A.
