Evaluating the LTC9101-3/LTC9103 16-Port, IEEE 802.3at PSE Controller with Power Management and LED Control

Overview

TopologyLAN / POE
Input voltage3.3 V

Description

The EVAL-LTC9101-3 is a 16-channel IEEE 802.3at compliant power sourcing equipment (PSE) with autonomous power management and serial LED driver for port LEDs. The EVAL-LTC9101-3 includes the EVAL-LTC9101-3-AZ daughter card, the EVAL-LTC9101-3-MBAZ motherboard, and features the LTC9101-3 and LTC9103 PSE platform chipset.In the EVAL-LTC9101-3, a single LTC9101-3 digital controller interfaces with up to two LTC9103, 8-channel, analog controllers for 16 power channels total. Up to sixteen IEEE 802.3af/at/bt powered devices (PDs) can be connected to the EVAL-LTC9101-3 and powered from this system using a single power supply.

Features

  • 16 Port IEEE 802.3at-compliant PSE
  • Autonomous Power Management with flash configuration
  • Serial LED driver for Port LEDs

Typical applications

  • Small Business PoE PSE Switches/Routers
