RS31312R

Hot Swap Controllers Overview

The RS31312R is a hot swap controller and electronic fuse (eFuse) manufactured by Reed Semiconductor Corp. It features an integrated pass MOSFET with a typical on-resistance of 2.7mΩ, designed for active circuit protection. The device supports a wide input voltage range from 4.5V to 16V and handles a maximum output current of 15A. Key programmable features include adjustable current limiting, adjustable hog-plug insertion time delay, and latched fault protection. It operates within a temperature range of -40°C to 125°C and is available in a 22-VFQFN exposed pad package.

Hot Swap Controllers Feature Summary

• Integrated high-current pass MOSFET for efficient power handling
• Adjustable current limit and hog-plug insertion time delay
• Latched fault protection mechanism for robust system safety

Hot Swap Controllers Applications

• Hot swap protection for backplane systems
• Active circuit protection in industrial equipment
• Current monitoring and limiting in server motherboards

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix to ensure correct packaging options such as cut tape or reel quantities. Confirm that the 22-VFQFN package dimensions align with your PCB footprint requirements. Check for RoHS compliance status and moisture sensitivity level details before finalizing procurement plans to ensure supply chain readiness.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution is required for voltages between 4.5V and 16V. It is suitable for applications needing precise current limiting and controlled insertion delays to prevent inrush currents. Ensure the thermal management design accommodates the 15A output capability and the specific package thermal characteristics.

Hot Swap Controllers Part Context

This part belongs to the RS313xx series of eFuses from Reed Semiconductor Corp., which are designed for general-purpose hot swap control. These devices integrate protection logic with power switches to simplify board-level protection designs compared to discrete solutions.

Hot Swap Controllers Replacement Considerations

Direct substitutes may include other 15A hot swap controllers with similar voltage ranges and QFN-22 packages. Verify pin compatibility and electrical specifications against alternatives like the RS31312 or generic equivalents before substitution.
