DS4560S-AR+

Overview

The DS4560S-AR+ is a hot-swap voltage controller and 12V hot-plug switch manufactured by Analog Devices Inc. (Maxim Integrated). It is designed to manage the insertion and removal of live circuit boards while limiting inrush current and preventing voltage sags on the system power bus. The device integrates high-side switching capabilities with comprehensive protection features, including overcurrent, overvoltage, and thermal shutdown, ensuring safe operation during hot-plugging events in industrial and telecommunications environments.

Feature Summary

• Integrated high-side power switch for controlled hot-plug insertion
• Active current limiting and foldback protection mechanisms
• Programmable soft-start to manage inrush current
• Comprehensive fault protection including thermal and overvoltage shutdown

Applications

• Hot-pluggable backplane systems
• Telecommunications equipment modules
• Industrial control board insertion
• Server and storage subsystem power management

Procurement Notes

Verify the specific suffix 'AR+' against the official datasheet to confirm temperature range and package variant. Ensure compatibility with the target system's voltage levels and current requirements. Cross-reference the manufacturer's latest documentation for any design-in updates or lifecycle status changes before finalizing procurement specifications.

Selection Notes

Select this component when active hot-swap control is required for 12V systems. Evaluate the need for programmable thresholds versus fixed internal limits. Consider the package type and thermal performance relative to the application's heat dissipation constraints. Verify that the integrated protection features align with the system's safety and reliability standards.

Part Context

This part belongs to the Maxim Integrated hot-swap controller family, which provides solutions for managing live board insertion. These controllers are critical for maintaining system uptime and protecting sensitive electronics from power bus disturbances during maintenance or expansion activities in modular hardware architectures.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements or functional equivalents within the same product line. Verify that any substitute component matches the electrical specifications and protection features required for the specific application environment.
