MIC2587-1BM

Hot Swap Controllers Overview

The MIC2587-1BM is a single-channel positive high-voltage hot-swap controller manufactured by Microchip Technology. It operates within an input voltage range of +10V to +80V, with a maximum absolute rating of 100V. The device supports a current limit of 1.23A and functions at supply voltages between 10V and 80V. It features programmable characteristics including current limiting, fault timeout, slew rate control, and UVLO. The component is housed in an 8-SOIC package and is rated for industrial operating temperatures from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides safe insertion and removal of boards for systems requiring live backplanes
• Features programmable current limiting, fault timeout, and slew rate control
• Includes power fail detection and latch-up fault protection

Hot Swap Controllers Applications

• Systems requiring safe board insertion into always-powered backplanes
• Positive voltage hot-swap applications
• General purpose hot-swap controller implementations

Hot Swap Controllers Procurement Notes

Verify the specific suffix '1BM' against the official Microchip datasheet to confirm pinout and functional equivalence with other MIC2587 variants. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Cross-reference the manufacturer part number with the distributor's catalog to avoid confusion with similar models like the MIC2587R series.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution is required for positive voltage hot-swap applications up to 80V. It serves as a pin-for-pin functional equivalent to the LT1641, facilitating direct replacements in existing designs. Consider the industrial temperature range if the application operates in harsh environments. Verify that the external MOSFET selection aligns with the 1.23A current limit capability.

Hot Swap Controllers Part Context

The MIC2587 series includes variants such as the MIC2587-1YM and MIC2587R-1YM. The MIC2587-1BM is part of this family of single-channel positive high-voltage hot-swap controllers. These devices are designed to manage power delivery during board insertion and removal, protecting both the system and the card from electrical stress.

Hot Swap Controllers Replacement Considerations

The MIC2587-1BM is a pin-for-pin functional equivalent to the LT1641. Designers may consider this substitution for legacy designs utilizing the LT1641, provided the voltage and current specifications meet the application requirements.
