Description
General part information
MAX5984 Series
The MAX5984 is a single-port, power-sourcing equipment (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.The MAX5984 provides input undervoltage lockout (UVLO), input overvoltage lockout, overtemperature detection, output voltage slew-rate limit during startup, and LED status indication.The MAX5984 is available in a space-saving, 28-pin TQFN (5mm x 5mm) power package, and is rated for the extended (-40°C to +85°C) temperature range.ApplicationsIndustrial Automation EquipmentPoE RepeatersSingle-Port PSE End-Point ApplicationsSingle-Port PSE Power Injectors (Midspan Applications)Switches/RoutersWireless LAN Access Point/WiMAX® Base Stations
