MIC2588-2YM-TR

Hot Swap Controllers Overview

The MIC2588-2YM-TR is a hot-swap voltage controller manufactured by Microchip Technology, designed for negative voltage applications. It integrates an N-channel power MOSFET and control circuitry in an 8-pin SOIC package. The device provides precise current limiting and soft-start capabilities to prevent bus collapse during insertion. Key electrical parameters include a maximum input voltage of 48V and a typical threshold voltage of 100mV for current sensing. It operates within a temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates high-side N-channel MOSFET with dedicated control logic
• Provides programmable current limiting and adjustable soft-start timing
• Ensures system stability by preventing back-driving and bus collapse

Hot Swap Controllers Applications

• PCI/PCI-X card edge connectors
• CompactPCI backplane systems
• Industrial I/O module insertion

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm the specific suffix 'TR' indicates tape-and-reel packaging if required for automated assembly. Check for obsolescence status as this part may be discontinued; request latest lifecycle documentation from the manufacturer before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component for negative voltage hot-swap applications requiring robust protection against inrush currents. Ensure the load current does not exceed the internal MOSFET limits. Verify that the external sense resistor values align with the desired current limit thresholds. Consider thermal dissipation requirements based on the SOIC-8 package constraints.

Hot Swap Controllers Part Context

This part belongs to the MIC2588 family of hot-swap controllers. It is distinct from positive voltage variants like the MIC2587. The '2YM' designation typically refers to the specific pinout and feature set optimized for standard PC/PCI interfaces. It serves as a critical interface component for safe board insertion in modular electronic systems.
