Si3471A-IM Single Port PSE Controller

The Si3471A-IM Single Port PoE PSE Controller is a fully IEEE 802.3bt compliant PSE available in a compact QFN38 package. It is designed and optimized for single Ethernet port applications, such as PoE injectors, mid-spans, and fiber to copper bridges.

The Si3471A-IM delivers PoE power in a small footprint. Simple configuration pins determine the maximum power the Si3471A-IM will deliver to a connected powered device. A preconfigured status LED driver further simplifies single port designs. No host MCU or firmware programming is needed to take full advantage of all the Si3471A-IM features!

Easy to understand and design with, the Si3471A-IM EVB uses a simple schematic, two-layer PCB, and efficient layout to show a complete Si3471A-IM solution.
