Single-Port, 40W, IEEE 802.3af/at PSE

Controller with Integrated MOSFET

General Description

Features

The MAX5984 is a single-port, power-sourcing equip-

ment (PSE) power controller designed for use in IEEE^®

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

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

DC and AC load-disconnect detections. The MAX5984

operates automatically without the need for any software

programming and features an integrated power MOSFET

and sense resistor. The device also supports new Class 5

and 2-Event classification for detection and classification

of high-power PDs. The MAX5984 provides up to 40W to

a single port (Class 5 enabled) and still provides high-

capacitance detection for legacy PDs.

S IEEE 802.3af/at Compliant

S Up to 40W for Single-Port PSE Applications

S Integrated 0.5I Power MOSFET and Sense

Resistor

S 2-Event Pin-Select (MAX5984A/MAX5984B)

S PD Detection and Classification

S Programmable Current Limit for Class 5 PDs

S High-Capacitance Detection for Legacy Devices

S Supports Both DC and AC Load Removal

Detections

The MAX5984 provides input undervoltage lockout

(UVLO), input overvoltage lockout, overtemperature

detection, output voltage slew-rate limit during startup,

and LED status indication.

S Current Foldback and Duty Cycle-Controlled

Current Limit

S LED Indicator for Port Status

S Direct Fast-Shutdown Control Capability

The MAX5984 is available in a space-saving, 28-pin

TQFN (5mm x 5mm) power package, and is rated for the

extended (-40NC to +85NC) temperature range.
