Product Description

The LTC4227CUFD-4#TRPBF is a Dual Slot Power IC combining the LTC4227 Hot Swap Controller with Linear Tech Surge Protector functionality, designed for safe hot-swapping in high-power dual-channel systems. It features two independent inputs supporting 4.5V to 40V operating range, driving external N-channel MOSFETs to regulate inrush current and protect against overcurrent, short-circuit, and overvoltage faults. Operating from -40°C to 125°C, it integrates I²C-compatible telemetry for real-time voltage/current monitoring, fault reporting, and programmable power limits. Ideal for server backplanes, industrial automation, and telecom equipment, its key strengths include adjustable foldback current limiting, ±1% accurate current sensing, and fast 2µs fault response. Drawbacks include dependency on external MOSFETs and limited compatibility with low-voltage (<4.5V) modules. The device excludes battery management, display interfaces, or proximity sensing functions.
