PD69104B1ILQ-TR

Overview

The PD69104B1ILQ-TR is a four-channel Power Sourcing Equipment (PSE) manager from Microchip Technology, designed for IEEE 802.3af and 802.3at standards. It operates within a supply voltage range of 44V to 57V and supports an industrial temperature range of –10°C to 85°C. The device integrates PSE management functions into a compact QFN-48 package, enabling efficient power and data transmission over single cables for network devices.

Feature Summary

• Integrates full PSE management capabilities for compliant PoE applications
• Supports simultaneous power and data delivery over single Ethernet cables
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial networking infrastructure requiring robust power distribution
• IEEE 802.3af/at compliant endpoint power sourcing equipment
• Embedded systems needing integrated PoE controller solutions

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration. Confirm the QFN-48 footprint matches your PCB layout requirements. Ensure compatibility with 44V–57V input rails. Check for any recent Product Change Notifications regarding assembly sites or labeling updates before finalizing procurement.

Selection Notes

Select this component when a dedicated four-channel PSE manager is required for industrial environments. It is suitable for designs adhering to IEEE 802.3af/at standards. Consider the QFN-48 package constraints and thermal dissipation needs. Verify that the operating voltage range aligns with your system's DC input specifications.
