MAX5982CETE+

Overview

The MAX5982CETE+ is a Hot Swap Voltage Controller designed for Powered Device (PD) applications in Power-over-Ethernet (PoE) systems. It complies with IEEE 802.3af and 802.3at standards, supporting Class 1 and Class 2 devices. The component integrates an isolation power MOSFET, detection logic, and classification circuitry within a 16-pin TQFN package.

Feature Summary

• Integrates an isolation power MOSFET for safe hot insertion into PoE ports
• Supports automatic detection and classification signatures per IEEE 802.3af/at standards
• Includes built-in current limiting to protect against short circuits and overloads

Applications

• IEEE 802.3af compliant Powered Devices
• IEEE 802.3at compliant Powered Devices
• Class 1 and Class 2 PoE system implementations

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm voltage thresholds or feature variations. Confirm RoHS compliance status directly with Analog Devices documentation. Check current lifecycle status as distribution availability may vary by region.

Selection Notes

Select this controller when designing PoE endpoints requiring integrated protection and classification. Ensure the design supports the required input voltage range of 31V to 60V. Verify that the TQFN-16 package fits the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the MAX5982 family of Hot Swap controllers from Maxim Integrated, now part of Analog Devices. These components are specialized for managing power delivery in Ethernet-based networks, replacing discrete solutions with a single integrated IC for reduced bill of materials.
