Quad, IEEE 802.3at/af PSE Controller

for Power-over-Ethernet

General Description

Features

The MAX5980 is a quad, power-sourcing equipment

S IEEE 802.3at/af Compliant

(PSE) power controller designed for use in IEEE

S 0.25I Current-Sensing Resistor

802.3at/af-compliant PSE. This device provides powered

device (PD) discovery, classification, current limit, and

load disconnect detection. The device supports both

fully automatic operation and software programmability.

The device also supports new 2-event classification and

Class 5 for detection and classification of high-power

PDs. The device supports single-supply operation, pro-

vides up to 70W to each port (Class 5 enabled), and still

provides high-capacitance detection for legacy PDs.

S Up to 70W per Port for PSE Applications

S 9-Bit Port Current and Voltage Monitoring

S I C-Compatible, 3-Wire Serial Interface

S Supports Single-Supply Operation

S High-Capacitance Detection for Legacy Devices

S Supports DC Load-Removal Detections

S Space-Saving, 32-Pin TQFN (5mm x 5mm) Power

The device features an I C-compatible, 3-wire serial

Package

interface, and is fully software configurable and pro-

grammable. The device provides instantaneous readout

Applications

PSE-ICM

of port current and voltage through the I C interface. The

device’s extensive programmability enhances system

flexibility, enables field diagnosis, and allows for uses in

other, nonstandard applications.

Power-Sourcing Equipment (PSE)

Switches/Routers

Midspan Power Injectors

The device is available in a space-saving, 32-pin TQFN

(5mm x 5mm) power package and is rated for the auto-

motive (-40NC to +105NC) temperature range.
