Linear Technology's LT4180 Virtual Remote Sense Controller

The LT4180 from Linear Technology is a cutting-edge solution designed to overcome the challenges of voltage drop in long cable runs. It intelligently compensates for voltage drops in wires connected to a remote load without the need for additional sense wires. This innovative product is ideal for distributed power supply systems where maintaining accurate voltage at the load is crucial.

Key Features

• Virtual Remote Sensing: The LT4180 uses a unique virtual remote sensing technique to correct for voltage drops in the power supply path. This ensures that the voltage regulation at the load is as accurate as if remote sense wires were directly connected.
• Wide Operating Range: The device can operate over a wide input voltage range, making it versatile for various applications, from industrial to automotive systems.
• Minimal Additional Components: It requires only a few external components to function, simplifying design and reducing overall system cost.
• Diagnostic Features: The LT4180 includes diagnostic features that help detect and report potential issues such as open-circuit and short-circuit conditions in the sense wires.

Applications

The LT4180 is particularly useful in applications where it is impractical to run dedicated sense wires or where such wires may be unreliable. Common applications include:

• Telecommunication systems
• Datacom infrastructure
• Industrial control systems
• Automotive electronics
• High-end consumer electronics

Technical Specifications

With its compact size and robust design, the LT4180 is a small but powerful component that enhances the performance and reliability of your power distribution system. It operates seamlessly in environments that demand high precision and can withstand the rigors of industrial applications.
