PD69104BILQ-TR

Overview

The PD69104BILQ-TR is a 4-channel Power over Ethernet (PoE) PSE controller supporting IEEE 802.3af and 802.3at standards. It integrates internal MOSFETs with an Rds(on) of 0.3 ohms and an internal DC/DC rectifier. The device features dynamic power management, emergency power management with three power good inputs, and direct LED drive interfaces for status indication. It supports pre-standard PD detection and provides real-time monitoring of voltage, current, power, and temperature per port via UART and I2C interfaces.

Feature Summary

• Integrates four channels with built-in MOSFETs and DC/DC rectifiers for complete PoE solution
• Supports IEEE 802.3af and 802.3at standards including two-event classifications
• Provides dynamic and emergency power management capabilities
• Enables real-time monitoring of electrical parameters and temperature

Applications

• Small and medium business (SMB) PoE applications
• Small office/home office (SOHO) PoE systems
• Home gateways requiring PoE+ functionality
• Small enterprise routers

Procurement Notes

Verify component authenticity through authorized Microsemi distributors. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review the latest product change notices for any updates regarding manufacturing sites or material compositions. Ensure compatibility with system voltage requirements and interface protocols before integration into final designs.

Selection Notes

Select this component for designs requiring integrated 4-port PoE management without external switches. It suits applications needing automated power sourcing equipment control with minimal host processor involvement. Consider its support for both af and at standards when designing for mixed legacy and modern powered devices. Evaluate thermal performance based on the specified total power consumption limits under different operational modes.

Part Context

This part belongs to the PD69104 family of PoE managers designed by Microsemi. It serves as a compact solution for integrating PoE capabilities into networking hardware. The device simplifies design by combining power management, analog circuitry, and digital control in a single package, reducing the bill of materials compared to discrete solutions.

Replacement Considerations

Microchip Technology recommends the PD77714T4ILQ-0101-0000-TR as a replacement. Verify pinout compatibility and software configuration differences when migrating from the PD69104 series to the newer PD77714 model.
