MAX5980GTJ+

Overview

The MAX5980GTJ+ is a quad-channel Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af and 802.3at standards. It operates within a supply voltage range of 32 V to 60 V, supporting up to 70 W output power per channel. The device features a current limit of 75 mA and draws 5 mA operating supply current. Designed for surface mount installation in a 32-TQFN package with an exposed pad, it functions reliably across temperatures from -40°C to +105°C.

Feature Summary

Integrates four independent PSE channels for simultaneous PoE and PoE+ port management
Complies with IEEE 802.3af and 802.3at standards for standardized power delivery
Supports high-power applications with up to 70 W output capability per channel
Operates within extended industrial temperature ranges for robust environmental performance

Applications

Power over Ethernet (PoE) midspan injectors
IEEE 802.3af/at powered network switches
PoE-powered LED lighting systems
Wireless access point power distribution units

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status via official documentation before integration. Ensure the 32-TQFN thermal pad soldering process meets IPC standards for reliable heat dissipation. Validate that the specific lot matches the required operational temperature range specifications.

Selection Notes

Select this controller when designing multi-port PoE infrastructure requiring strict adherence to IEEE 802.3af/at protocols. Consider the 32-TQFN footprint for space-constrained PCB layouts. Evaluate the 70 W power rating against load requirements. Ensure input voltage capabilities align with the 32 V to 60 V operating window for stable system performance.
