PD70100ILD-TR

Overview

The PD70100ILD-TR is a single-channel Powered Device (PD) front-end interface controller designed for IEEE 802.3af Power over Ethernet applications. Manufactured by Microchip Technology, this component integrates the necessary logic and analog functions to manage power negotiation and delivery on an Ethernet link. It operates within a supply voltage range of 0V to 57V and supports a maximum power consumption of 15.4W per channel. The device is housed in a compact 12-lead VDFN package with exposed pad, suitable for surface mount assembly. It features an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Integrates complete IEEE 802.3af compliant Powered Device front-end functionality
• Supports Class 0 through Class 3 power classification levels
• Includes integrated linear regulator for internal biasing
• Features low standby current consumption during idle states

Applications

• IP cameras and video surveillance systems
• Wireless access points and network switches
• VoIP telephones and communication endpoints
• Industrial IoT sensor nodes requiring PoE power

Procurement Notes

Verify the specific suffix ILD-TR against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your system's voltage rails and thermal management requirements. Confirm RoHS compliance status and moisture sensitivity level prior to PCB assembly. Cross-reference the ordering part number with official Microchip documentation to avoid substitution errors.

Selection Notes

Select this component when designing systems strictly adhering to the IEEE 802.3af standard for power delivery. It is appropriate for single-port applications where cost-effective integration of PoE PD logic is required. Consider thermal dissipation capabilities given the 15.4W maximum power limit. Evaluate board space constraints as the VDFN package offers a small footprint compared to larger alternatives.

Part Context

This part belongs to Microchip's PD70100 series of PoE controllers, which are specialized for powering remote devices over Ethernet cabling. The series provides a solution for manufacturers needing to add PoE capability without complex discrete designs. It sits within the broader Power Management IC category, specifically under Switch ICs for LAN applications.

Replacement Considerations

Check for updated revisions within the PD70100 family. Verify pin-to-pin compatibility if considering alternative vendors. Ensure any substitute maintains IEEE 802.3af certification for regulatory compliance.
