The component distinguishes between LTPoE++ and IEEE standards via its T2P output, ensuring compatibility with high-power PoE LAN infrastructure while maintaining strict adherence to industry communication protocols for reliable power delivery.
Feature Summary
- Complies with LTPoE++ and IEEE 802.3af/at/bt standards for powered device interfaces
- Distinguishes between LTPoE++ and IEEE protocols using the T2P output signal
- Designed for integration into Power over Ethernet LAN infrastructure
Applications
- LTPoE++ compliant powered device systems
- IEEE 802.3bt powered device implementations
- Standard PoE and PoE+ network endpoint controllers
Procurement Notes
Verify that the specific order matches the LT4293IDD#TRPBF designation to ensure correct packaging and pinout configuration. Confirm compatibility with the target system's voltage requirements and protocol support before finalizing procurement. Ensure sourcing from authorized channels to guarantee component authenticity and datasheet accuracy.
Selection Notes
Select this controller when designing systems requiring support for both legacy IEEE PoE standards and newer LTPoE++ specifications. The integrated protocol distinction feature simplifies design complexity by handling standard identification internally. Ensure the application environment supports the required operating conditions specified in the official documentation.
Part Context
This component belongs to the LT429 series of Power Over Ethernet controllers from Analog Devices. It serves as a specialized interface solution for managing power delivery in modern networked devices. The part integrates essential control logic to handle complex power negotiation processes required by current Ethernet standards.
Replacement Considerations
Consult official Analog Devices documentation for verified substitute part numbers. Do not assume cross-compatibility with other PoE controllers without verifying pinout and protocol support alignment.
