MIC2587R-1BM

Hot Swap Controllers Overview

The MIC2587R-1BM is a single-channel, positive high-voltage hot-swap controller manufactured by Microchip Technology. It is designed to provide safe insertion and removal of boards in systems requiring live backplanes. The device operates with an input voltage range of 10 V to 80 V and features adjustable current limiting, fault timeout, slew rate control, and UVLO. It is housed in an 8-SOIC package and supports surface-mount installation. The component functions without an internal switch, requiring an external N-channel MOSFET for power path control.

Hot Swap Controllers Feature Summary

• Provides safe board insertion and removal for always-powered backplane systems
• Features programmable current limiting, fault timeout, and slew rate control
• Includes auto-retry functionality for transient fault recovery
• Supports lockout fault detection for persistent error conditions

Hot Swap Controllers Applications

• Telecommunications equipment with live backplanes
• Industrial control systems requiring hot-swappable modules
• Data communication infrastructure with high-voltage power buses

Hot Swap Controllers Procurement Notes

Verify the specific suffix '1BM' against the official Microchip datasheet to confirm packaging type (tube/rail) and pin configuration. Ensure compatibility with external MOSFET selection based on the 10 V to 80 V operating range. Confirm RoHS compliance status as per the latest product change notices. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar variants like the -1YM or -TR versions.

Hot Swap Controllers Selection Notes

Select this controller when designing systems that require precise control over inrush current and fault response for high-voltage DC inputs up to 80 V. It is suitable for applications needing adjustable slew rates to minimize bus disturbances during board insertion. Consider the 8-SOIC package constraints for PCB layout. Verify that the external MOSFET chosen can handle the maximum input voltage and current limits defined by the controller's programming resistors.

Hot Swap Controllers Part Context

The MIC2587R series belongs to Microchip's portfolio of hot-swap controllers, derived from Micrel's original design lineage. These components are engineered for robust protection in high-voltage environments where system uptime is critical. The 'R' variant typically denotes specific feature sets or revisions within the family, focusing on reliable operation in telecommunications and industrial sectors.
