SI3404-A-GM
by SKYWORKS/SILICON LABS(芯科)Power-over-Ethernet equipment uses a powered-device interface to receive power through its Ethernet connection. The SI3404-A-GM belongs to this PoE power-management family and is intended for the receiving side of that link. Its surface-mount QFN footprint includes an exposed-pad feature. Available KiCad files include a 21-pin symbol, the QFN-20_L4.0-W4.0-P0.50-BL-EP2.7 footprint with 21 pads, and an included 3D model. These files originate from a real ProtoFlow import, with the conversion checked in the editor. The complete part can be opened directly in ProtoFlow for schematic placement and board work.
