SI3462 Datasheet Single-port Ieee 802.3at Poe/poe+ Pse Interface

Manufacturer: Silicon Laboratories

Overview: Si3462 SINGLE-PORT IEEE 802.3AT POE/POE+ PSE INTERFACE.

General Description

The Si3462 is a single-port power management controller for IEEE 802.3atpliant Power Sourcing Equipment (PSE).

The Si3462 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.
