MAX5952CEAX+

Overview

The MAX5952CEAX+ is a quad Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af and 802.3at standards. It supports input supply voltages from 32V to 60V with a typical supply current of 4.8mA. The device delivers up to 45W of total power across four channels without internal switches, housed in a 36-SSOP package. It operates within a temperature range of 0°C to +85°C.

Feature Summary

• Supports IEEE 802.3af and 802.3at PoE/PoE+ standards for remote powering
• Integrates quad PSE controller functionality for multi-port applications
• Features successive approximation register architecture for control

Applications

• Power over Ethernet infrastructure equipment
• Multi-port network switches requiring centralized PSE management
• Remote device powering systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to obsolete lifecycle status. Confirm RoHS compliance details via official datasheets. Check regional availability restrictions as distribution may be limited. Validate package integrity upon receipt.

Selection Notes

Select this component for designs requiring quad-channel PoE control without integrated switches. Ensure system voltage aligns with the 32V to 60V input range. Consider thermal management for the 36-SSOP package in enclosed environments. Verify compatibility with existing IEEE 802.3af/at implementations.

Part Context

Part of the MAX5952 series, this controller complements other hot-swap solutions like the MAX5902. It serves as a specialized PMIC for power management in networking hardware, distinct from LED drivers or comparators in the Maxim portfolio.
