MAX5996CATE+

Overview

The MAX5996CATE+ is a high-performance, IEEE 802.3bt-compliant Powered Device (PD) controller manufactured by Analog Devices Inc./Maxim Integrated. It supports detection and classification feature profiles for PoE applications up to 90W. The device integrates an input voltage withstand capability of 100V, surge current limiting during startup, and intelligent Multi-Protocol Signaling (MPS). It operates within a temperature range of -40°C to +125°C in a 16-pin, 5mm x 5mm TQFN package.

Feature Summary

• IEEE 802.3bt compliance with integrated 90W isolation switch
• Input voltage withstand up to 100V with wide UVLO hysteresis
• Surge current limiting at startup and multi-event classification
• Supports LLDP power/level readings and smart MPS

Applications

• VoIP telephones
• IP security cameras
• Wireless access points
• Small cell and picocell base stations
• Building automation systems

Procurement Notes

Verify the specific suffix 'CATE+' against official datasheets to confirm package type and temperature rating. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3bt standards. Ensure thermal management aligns with the TQFN-EP-16 package capabilities. Validate that system requirements match the 100V input withstand and 90W power delivery specifications.

Part Context

This part belongs to the MAX5996 series of PoE controllers designed for high-power Ethernet applications. It replaces older PD solutions by supporting higher power budgets and advanced signaling protocols like LLDP and Smart MPS for improved network integration.
