MIC2585-1LYTS

Hot Swap Controllers Overview

The MIC2585-1LYTS is a dual-channel hot-swap controller and sequencer manufactured by Microchip Technology. It provides precise control for inserting and removing cards from live backplanes, managing inrush current and output voltage ramping. The device features a 100mV threshold for current sensing and includes integrated fault protection mechanisms such as over-voltage, under-voltage, and thermal shutdown. Packaged in a 24-pin TSSOP, it supports independent channel operation or synchronized sequencing for multi-rail applications.

Hot Swap Controllers Feature Summary

• Dual-channel architecture enabling independent or sequential power-up management
• Integrated high-side N-channel MOSFET drivers with adjustable current limit thresholds
• Comprehensive fault protection including over-voltage, under-voltage, and thermal shutdown
• Supports controlled inrush current limiting to prevent bus collapse during insertion

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe card insertion
• Industrial control systems with modular I/O racks
• Data center server backplanes managing multiple power rails
• Test and measurement instruments needing controlled power sequencing

Hot Swap Controllers Procurement Notes

Verify component status carefully as this part may be obsolete or not recommended for new designs. Confirm availability through authorized distributors only. Ensure compatibility with existing board layouts due to the specific TSSOP-24 package dimensions. Review latest datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot-swap capability is required for system reliability. Consider the 100mV sense threshold for appropriate load current ranges. Evaluate the TSSOP-24 package constraints against PCB space limitations. Compare against single-channel alternatives if only one rail requires protection. Verify thermal performance requirements given the integrated driver capabilities.
