Frequently Asked Questions
What is the maximum power that LT4294IDD#TRPBF can deliver as a PoE++ PD?
The LT4294IDD#TRPBF supports IEEE 802.3bt Type 3 and Type 4 operation, enabling a powered device to receive up to 90 W from a compliant PSE over a standard Ethernet cable, making it ideal for high-power applications.
What input voltage range does LT4294IDD#TRPBF accept from the Power Sourcing Equipment?
The LT4294IDD#TRPBF operates from a PSE-supplied input voltage range of approximately 37 V to 57 V, covering the full IEEE 802.3bt specification and allowing robust operation across all compliant PoE++ power sourcing equipment.
How does the integrated hot-swap controller in LT4294IDD#TRPBF protect the downstream system during power-up?
The built-in hot-swap controller limits in-rush current during power-up with a controlled ramp, preventing voltage transients from exceeding safe limits. It uses a 100 mΩ sense resistor pathway and precise current regulation to ensure safe and repeatable power-on sequencing for sensitive 3.3 V or 5 V downstream loads.
When would LT4294IDD#TRPBF be preferred over a discrete PoE PD solution in a PCB design?
LT4294IDD#TRPBF integrates signature, classification, and hot-swap functions in a 10-lead DFN package measuring approximately 3 mm x 3 mm, dramatically reducing BOM count and PCB area compared to discrete implementations, which is especially valuable in space-constrained designs for cameras or access points.
Which IEEE 802.3bt PD classes does LT4294IDD#TRPBF support for power classification negotiation?
LT4294IDD#TRPBF supports PD class negotiation for IEEE 802.3bt classes up to Class 8, corresponding to 90 W maximum power allocation, and includes the 2-event physical layer classification handshake required for Type 3 and Type 4 high-power powered device recognition.
