SI3462 - SINGLE-PORT IEEE 802.3AT POE/POE+ PSE INTERFACE

Description

The Si3462 is a single-port power management controller for IEEE 802.3atcompliant 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.

Features

  • IEEE 802.3atTM compliant PSE.
  • Short-circuit output fault.
  • Autonomous operation requires no protection host processor interface.
  • LED status signal (detect,.
  • Complete reference design power good, output fault) available, including Si3462 controller.
  • UNH Interoperability Test Lab and schematic: report available.
  • Low-cost BOM.
  • Extended operating range.
  • Compact PCB footprint (.
  • 40 to +85 °C).
  • Operates directly from a +50 V.
