LT4293IMS#PBF

Overview

The LT4293IMS#PBF is a Powered Device (PD) interface controller compliant with IEEE 802.3af, 802.3at, and 802.3bt standards. It operates within a supply voltage range of up to 60V and supports an operating temperature range from -40°C to +125°C. The device features a low quiescent current of 2mA and is housed in a 10-lead MSOP package suitable for surface mount installation.

Feature Summary

• Supports LTPoE++ and IEEE 802.3bt Powered Device classification
• Integrated control interface for power sourcing equipment communication
• Extended industrial temperature rating for harsh environments

Applications

• IEEE 802.3bt Type 3 and Type 4 Powered Devices
• LTPoE++ compatible endpoint hardware
• Industrial networking equipment requiring extended temperature operation

Procurement Notes

Verify the specific suffix IMS against official Analog Devices documentation to confirm the temperature grade and package variant. Ensure compatibility with the target system's voltage requirements and thermal management design before procurement.

Selection Notes

Select this component when designing systems requiring support for high-power PoE standards including LTPoE++. Consider the MSOP-10 package constraints and the need for robust thermal dissipation given the 125°C maximum operating temperature rating.

Part Context

This part belongs to the LT4293 family of PoE PD controllers manufactured by Analog Devices. It is designed to work in conjunction with PSE controllers to facilitate power delivery over Ethernet cables while managing classification and fault protection protocols.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic cross-references may not match the specific LTPoE++ support or thermal characteristics required.
