RS31310AR

Hot Swap Controllers Overview

The RS31310AR is a single-channel hot-swap controller manufactured by Reed Semiconductor Corp. Designed for PCI and PCI-X applications, it integrates an internal switch to manage power sequencing and protection. The device operates within a supply voltage range of 2.97V to 16.5V and supports a maximum output current of 5A. It features programmable current limiting capabilities to safeguard connected components during insertion or fault conditions. The IC is housed in a compact 10-VSON (3x3) package with exposed pad, suitable for surface mount assembly. It functions reliably across an industrial temperature range from -40°C to +125°C.

Hot Swap Controllers Feature Summary

• Integrates an internal power switch for direct load control without external MOSFETs
• Provides programmable current limiting to protect against overcurrent events
• Includes fail-safe mechanisms to ensure known states during power loss or floating inputs

Hot Swap Controllers Applications

• PCI bus hot-swap systems
• PCI-X backplane applications
• Server and storage system power management

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling but not electrical function. Confirm the manufacturer part number matches exactly to avoid confusion with similar thermal management ICs. Check the latest datasheet for any updates on pinout or recommended operating conditions before finalizing design integration.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring integrated hot-swap protection for PCI or PCI-X interfaces. It is suitable for applications needing a single-channel solution with built-in current limiting and internal switching. Consider the 10-VSON package size for space-constrained designs. Ensure the supply voltage range aligns with the system's power rails and that the 5A current rating meets the load requirements.

Hot Swap Controllers Part Context

This part belongs to the category of Power Management ICs, specifically under Hot-Swap Controllers. These devices are essential for managing the insertion and removal of cards in live systems. The RS31310AR addresses the need for robust protection in high-speed data buses like PCI and PCI-X, ensuring system stability during dynamic power changes.

Hot Swap Controllers Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided documentation. Engineers should consult the manufacturer for potential alternatives or cross-reference based on specific pin-to-pin compatibility and electrical specifications if a replacement is required.
