SI3461 Datasheet SINGLE-PORT IEEE 802.3AT POE/POE PSE INTERFACE

Manufacturer: Silicon Laboratories

General Description

The Si3461 is a single-port power management controller for IEEE 802.3at-compliant Power Sourcing Equipment (PSE).

The Si3461 can be powered from a 50 V input using a shunt regulator, or, to save power, it can be powered from 50 V and 3.3 V power supplies.

The IEEE-required Powered Device (PD) detection
