LT4293HDD#TRPBF

Overview

The LT4293HDD#TRPBF is a Powered Device (PD) interface controller compliant with IEEE 802.3af, 802.3at, and LTPoE++ standards. It operates within a supply voltage range of 60 V and supports a quiescent current of 2 mA. The device functions reliably across an extended temperature range from -40°C to +125°C. It utilizes a DFN-10 surface-mount package for integration into PoE-powered systems.

Feature Summary

• Supports LTPoE++ and standard IEEE 802.3af/at protocols
• Integrated Powered Device interface control
• Extended industrial temperature operation capability

Applications

• PoE-powered surveillance cameras
• Wireless access points
• Industrial IoT sensor nodes

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the DFN-10 footprint matches your PCB layout requirements. Ensure compatibility with the target PoE power sourcing equipment standards before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring strict adherence to LTPoE++ and legacy IEEE 802.3af/at standards. The wide operating voltage range suits high-voltage PoE environments. Consider the thermal performance of the DFN-10 package for dense circuit board layouts.

Part Context

This part belongs to Analog Devices' portfolio of Power over Ethernet controllers. It complements other PD interface solutions by supporting advanced LTPoE++ capabilities alongside traditional standards. The series focuses on reliable power detection and classification in networked devices.

Replacement Considerations
