LT4200RUHG#TRPBF

Hot Swap Controllers Overview

The LT4200RUHG#TRPBF is an integrated hot swap controller and power MOSFET designed for high-current applications. It provides a complete solution for safely inserting or removing boards from live backplanes. The device features a co-packaged MOSFET with guaranteed Safe Operating Area (SOA) to withstand hot swap stresses. It supports continuous operation at 50 A up to +85°C ambient temperature. Key electrical characteristics include a 57 A current limit with ±12% accuracy, independent inrush current control, and output-related foldback. The input voltage rating allows survival of transients exceeding the maximum operating voltage.

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part matches the RUHG package type. Check for RoHS compliance status in official documentation. Validate that the component is suitable for the required thermal environment.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust hot swap capabilities without external MOSFETs. The integrated design reduces board space and simplifies schematic complexity. Consider the 50 A continuous current capability for high-power bus architectures. Evaluate the need for dynamic current limit adjustment using the ISET pin. Ensure the system voltage does not exceed the absolute maximum ratings.

Hot Swap Controllers Part Context

This part belongs to the LT4200 family of hot swap controllers. It combines control logic with a power switch to manage insertion and removal events. The family is designed for protecting sensitive electronics during maintenance or expansion. It eliminates the need for discrete components typically used in hot swap circuits.
