What are the key features of LT4275BIMS#TRPBF?
- IEEE 802.3at PoE+ PD controller manages detection, classification, and inrush limiting in a single 8-pin MSOP IC
- Industrial temperature grade ensures reliable operation across the full -40°C to +85°C ambient range in harsh deployments
- 260°C peak reflow compatibility with matte tin finish supports standard lead-free PCB assembly processes
- Compact MSOP-8 package minimizes PCB footprint for PoE-powered network cameras, VoIP phones, and access points
What is LT4275BIMS#TRPBF used for?
The LT4275BIMS#TRPBF is designed for IEEE 802.3at PoE+ powered devices such as IP security cameras, wireless access points, VoIP phones, and industrial Ethernet sensors that draw power directly from a PoE-enabled Ethernet switch or midspan injector. It handles the mandatory IEEE 802.3at detection and classification handshake, inrush current limiting, and power-good signaling, greatly simplifying PoE PD compliance. Its industrial temperature rating makes it suitable for outdoor enclosures and factory-floor network devices operating from -40°C to +85°C.

Frequently Asked Questions
Which IEEE PoE standard does the LT4275BIMS#TRPBF support, and what maximum power can a compliant PD device draw?
The LT4275BIMS#TRPBF supports IEEE 802.3at (PoE+), which allows a powered device to draw up to 25.5 W from the Ethernet cable pair. This doubles the 15.4 W limit of the earlier IEEE 802.3af standard, enabling higher-power devices like pan-tilt cameras, 802.11ac access points, and industrial Ethernet I/O modules to be powered over standard CAT5e or CAT6 cable.
How does the LT4275BIMS#TRPBF simplify meeting IEEE 802.3at compliance requirements for a powered device design?
The LT4275BIMS#TRPBF integrates the IEEE 802.3at signature resistor detection, class 4 power classification, and inrush current limiting into a single 8-pin MSOP IC. Without this controller, designers must implement these functions discretely with external FETs, resistors, and timing circuits. A single-chip solution reduces BOM count, shrinks PCB area, and ensures the detection and classification waveforms meet the 802.3at timing specifications without custom tuning.
For an outdoor IP camera operating in direct sunlight near a rooftop, how does the industrial temperature rating of the LT4275BIMS#TRPBF help ensure reliability?
The LT4275BIMS#TRPBF carries an industrial temperature grade, guaranteeing specified operation from -40°C to +85°C. Outdoor enclosures exposed to direct sunlight can reach internal temperatures above +70°C in summer, while winter installations may drop below -20°C. The -40°C lower limit ensures the PoE PD controller starts and operates reliably across all seasons without derating or heater provisions.
