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  
2
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.
