MIC2589R-1YM-TR

Hot Swap Controllers Overview

The MIC2589R-1YM-TR is a negative voltage hot-swap controller manufactured by Microchip Technology. It is designed for safe insertion and removal of circuit boards in live systems, specifically managing negative power rails. The device operates within a supply voltage range of 10 V to 80 V and supports adjustable current limiting to protect against overcurrent conditions. It features a single channel configuration and is housed in an SOIC-14 surface-mount package. The component functions across an industrial temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides controlled ramp-up of negative voltage during board insertion to prevent system glitches
• Includes adjustable current limit protection to safeguard the load and source during fault conditions
• Integrates thermal shutdown to protect the device from overheating during sustained overload events

Hot Swap Controllers Applications

• Hot-plug management for negative power rails in telecommunications equipment
• Safe insertion and removal of backplanes in data communication systems
• Protection circuits for high-voltage negative bus architectures in industrial control panels

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the application requires negative voltage handling, as this controller is not suitable for positive rail hot-swap applications. Ensure the input voltage does not exceed the 80 V maximum rating. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring hot-swap capability for negative voltage supplies up to 80 V. It is appropriate for applications needing adjustable current limiting rather than fixed thresholds. Consider the SOIC-14 package size for PCB layout constraints. Evaluate the need for thermal protection features inherent in the design before choosing over simpler switch ICs.

Hot Swap Controllers Part Context

This part belongs to the MIC2589 family of hot-swap controllers from Microchip Technology, which originated from Micrel. The family focuses on protecting high-voltage systems during dynamic connection events. The 'R' variant typically denotes specific revision or feature set differences compared to non-R versions, though functional core remains consistent with negative voltage hot-swap requirements.
