Key Features
- Supports IEEE 802.3bt Type 3 (60W) and Type 4 (90W) PoE++ with up to 71.3W delivered power from a 60V PoE input rail
- Integrated PD detection, classification, and power-on sequencing eliminate the need for external MOSFET switch and supervisor ICs
- 10-pin MSOP package occupies less than 10mm² of PCB area, enabling compact PoE++ PD designs in space-constrained network devices
- Autonomous operation requires minimal external components (resistors and capacitors only) simplifying BOM and reducing design complexity
- Wide industrial temperature range (-40°C to 85°C) supports outdoor and extended-environment PoE endpoint deployments
Applications
The LT4294IMS#TRPBF is used in high-power PoE++ powered device designs such as 802.11ax/ac outdoor wireless access points, PTZ IP security cameras, and high-resolution network video recorders that require more than 30W from a single Ethernet port. Building automation controllers, smart building IoT gateways, and PoE-powered thin clients benefit from its ability to request and receive up to 71.3W without an additional power brick. It also suits industrial VoIP phones and conference room AV equipment where a single CAT6 cable must carry both data and up to 60W of operating power.

Frequently Asked Questions
What maximum power can the LT4294IMS#TRPBF deliver to a PoE++ powered device?
The LT4294IMS#TRPBF enables a powered device (PD) to receive up to 71.3W from a 60V IEEE 802.3bt Type 3 PoE++ input rail. This power budget supports high-demand applications such as PTZ cameras with built-in heaters, 802.11ax 4×4 MIMO outdoor access points, and multi-screen thin clients — all powered through a standard CAT5e or CAT6 Ethernet cable without a local power adapter.
How does the LT4294IMS#TRPBF simplify board design compared to discrete PoE PD controller implementations?
The LT4294IMS#TRPBF integrates the PoE detection resistor interface, class-1 through class-8 current signature, power-on switch control, and inrush current limiting into a single 10-pin MSOP IC. A discrete implementation of these functions typically requires a PD controller, external N-channel MOSFET, TVS diode, and several precision resistors, consuming 3–4× more PCB area and adding 5–8 additional components to the BOM.
At what input voltage range does the LT4294IMS#TRPBF operate, and is it compatible with both 802.3af and 802.3at PSEs?
The LT4294IMS#TRPBF operates from a 30V to 60V PoE input, making it compatible with IEEE 802.3af (37V–57V, up to 12.95W at the PD), 802.3at Type 2 (42.5V–57V, up to 25.5W), and 802.3bt Type 3 and Type 4 (50V–57V, up to 71.3W) power sourcing equipment. This backward compatibility allows a single PCB design to support legacy and next-generation PoE+ and PoE++ infrastructure.
What operating temperature range does the LT4294IMS#TRPBF support for outdoor PoE device deployments?
The LT4294IMS#TRPBF is rated for operation from -40°C to 85°C (industrial grade), making it suitable for outdoor PoE devices such as pole-mounted PTZ cameras and parking lot access points that must operate through winter cold at -30°C ambient and summer roof temperatures exceeding 70°C. The wide temperature range eliminates the need for thermostatically controlled heaters in most mid-latitude outdoor enclosures, reducing total system power consumption.
