Product Description

The LTC4235IUFD-1#PBF is a Hot Swap Controller IC from Linear Technology designed to safely manage inrush current and protect circuits during board insertion or removal in high-power systems. It features a single input channel supporting up to 80V operating voltage range and integrates robust fault protection, including overcurrent, undervoltage, and overtemperature detection. The IC directly interfaces with external MOSFETs to control multiple power modules, ensuring reliable hot-swapping in industrial applications such as telecom equipment, servers, and distributed power systems. Operating across -40°C to 125°C, it offers fast response times and adjustable current limiting via external resistors. While it lacks built-in communication interfaces, its compact design and high reliability make it ideal for rugged environments. Parameters like battery capacity, screen size, and detection distance are not applicable to this controller-focused IC.
