LTC9101AUF-2#TRPBF

Overview

The LTC9101AUF-2#TRPBF is a Power Sourcing Equipment (PSE) controller designed for IEEE 802.3bt PoE applications. It operates within a supply voltage range of 51 V to 57 V and supports up to 90 W output power. The device features a maximum on-resistance of 30 mOhms and draws 40 mA of supply current. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 24-lead QFN package.

Feature Summary

• Supports IEEE 802.3at, 802.3af, and 802.3bt standards
• Integrated high-efficiency power switch with low on-resistance
• Designed for multi-port PSE implementations

Applications

• IEEE 802.3bt Power Sourcing Equipment controllers
• Multi-port PoE network infrastructure
• High-power LAN power distribution systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the 24-WFQFN exposed pad package dimensions. Check RoHS compliance status through official documentation before integration.

Selection Notes

Select this component for designs requiring full IEEE 802.3bt compatibility. It is suitable for applications needing integrated switching capabilities within a compact footprint. Consider the 51 V to 57 V input requirement and thermal management needs for the QFN package during PCB layout.
