MAX5980GTJ+T

Overview

The MAX5980GTJ+T 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 32V to 60V, drawing a typical supply current of 5mA. The device supports a maximum output power of 70W across its four channels. It is housed in a 32-WFQFN package with an exposed pad, designed for surface-mount installation. The operational temperature range spans from -40°C to +105°C.

Feature Summary

• Integrates control logic for four independent PoE channels supporting both legacy and high-power standards
• Provides comprehensive protection mechanisms including overvoltage, undervoltage, and thermal shutdown
• Features programmable slew rate control to minimize inrush currents during port activation

Applications

• Power Sourcing Equipment (PSE) modules for enterprise networking switches
• Wireless access point power distribution systems
• Industrial IoT gateway power management units

Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the component meets RoHS3 compliance requirements for your target market. Ensure that the 32-TQFN footprint matches your PCB layout guidelines precisely. Check for any recent lifecycle status updates or obsolescence notices from Analog Devices.

Selection Notes

Select this controller when designing multi-port PoE infrastructure requiring support for both 802.3af and 802.3at protocols. It is suitable for applications needing centralized management of up to four powered devices. Consider the thermal performance of the exposed pad design for high-density board layouts. Evaluate the external MOSFET selection to ensure compatibility with the controller's drive capabilities.
