LT4294IMS#TRPBF

Overview

The LT4294IMS#TRPBF is a hot swap voltage controller designed for IEEE 802.3bt Powered Device (PD) applications. It operates within an input voltage range of 8 V to 60 V and features adjustable current limiting. The device supports single-channel operation with a typical operating supply current of 2 mA. It is rated for commercial temperatures from -40°C to +85°C and is housed in a 10-lead DFN package.

Feature Summary

• Integrated interface controller compliant with IEEE 802.3bt standards
• Adjustable current limit protection for load management
• Supports hot swap insertion without system disruption

Applications

• IEEE 802.3bt Type 3 and Type 4 Powered Devices
• Power over Ethernet endpoint integration
• High-power network equipment interfaces

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure the component matches the required thermal and electrical specifications for the target application before procurement.

Selection Notes

Select this component for designs requiring certified IEEE 802.3bt PD control. Confirm that the 60 V maximum input rating and DFN-10 footprint align with the system's power budget and PCB layout constraints.

Part Context

This part belongs to the LT4294 series of hot swap controllers. It serves as a specialized interface solution for managing power delivery in high-voltage PoE environments, distinct from lower-power PoE+ or standard PoE controllers.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout and functional equivalence with other IEEE 802.3bt PD controllers if sourcing changes are necessary.
