MAX5952AUAX+T

Overview

The MAX5952AUAX+T is a quad Power Sourcing Equipment (PSE) controller designed for IEEE 802.3af and 802.3at PoE applications. It operates within a supply voltage range of 32V to 60V with a typical supply current of 4.8mA. The device supports up to 45W of total power across four channels and functions within an operating temperature range of 0°C to +85°C. Packaged in a 36-SSOP, it integrates classification and management features without internal switches.

Feature Summary

• Supports IEEE 802.3af and 802.3at standards for PoE power sourcing
• Provides four independent channel controllers for simultaneous port management
• Integrates classification logic to identify powered device power requirements

Applications

• PoE-powered network infrastructure equipment
• Wireless access point power distribution systems
• IP camera power sourcing modules

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to discontinuation status. Confirm package integrity and pin alignment against the 36-SSOP specification before integration. Request lot traceability documentation to ensure compliance with RoHS and REACH regulations required for modern manufacturing environments.

Selection Notes

Select this component when designing multi-port PoE injectors or midspan devices requiring integrated classification. Ensure the design accommodates the 32V to 60V input range and thermal dissipation needs for 45W total load. Verify that the absence of internal switches aligns with the external switch topology planned for the target application architecture.

Part Context

This part belongs to the MAX5952 family of hot-swap voltage controllers specialized for Ethernet power applications. It serves as a dedicated PSE controller distinct from PD controllers like the MAX5992. The 'T' suffix indicates tape-and-reel packaging, while the '+' denotes lead-free compliance within the Maxim Integrated product line.

Replacement Considerations

Public records indicate the MAX5952 series has reached end-of-life status. No direct public substitute part numbers are confirmed for this specific quad-channel configuration.
