MAX5980AGTJ+T

Overview

The MAX5980AGTJ+T is a quad 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 and draws a typical operating current of 5 mA. The device supports a maximum output power of 70 W per channel and includes a 75 mA current limit feature. Designed for surface mount installation, it utilizes a TQFN-EP-32 package and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent PSE channels supporting PoE and PoE+ classifications
• Complies with IEEE 802.3af and 802.3at standards for standardized power delivery
• Includes internal protection mechanisms such as current limiting and thermal shutdown

Applications

• Power over Ethernet switches and hubs
• Wireless access points requiring integrated PSE functionality
• Network infrastructure equipment needing multi-channel power sourcing

Procurement Notes

Verify the specific suffix 'GTJ' against official Analog Devices documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status directly with authorized distributors as supply constraints may apply to this series.

Selection Notes

Select this component when designing systems requiring four isolated PoE/PoE+ ports without external discrete switches. Verify that the input voltage range aligns with your system's bus architecture. Ensure the thermal management solution accommodates the TQFN-EP-32 package dissipation characteristics under maximum load conditions.
