MIC2593-2BTQ-TR

Hot Swap Controllers Overview

The MIC2593-2BTQ-TR is a dual-slot PCI hot-plug controller manufactured by Microchip Technology. It supports PCI and PCI-X standards, featuring ten channels for power management. The device operates with N-channel external switches and handles positive and negative voltage rails, specifically 12.6V, -11V, 5.25V, and 3.6V. It is housed in a 48-pin TQFP package (7x7 mm) and includes SMBus interface capabilities. The component provides latched fault protection and thermal shutdown to ensure system integrity during insertion or removal events.

Hot Swap Controllers Feature Summary

• Supports dual-slot PCI and PCI-X hot-plug applications

Hot Swap Controllers Procurement Notes

Verify the manufacturer marking matches Microchip Technology. Confirm the package type is 48-TQFP. Check for lead-free compliance and RoHS certification status on the datasheet. Ensure the suffix indicates tape and reel packaging if required for automated assembly. Validate the part number against official Microchip documentation to avoid counterfeit components.

Hot Swap Controllers Selection Notes

Select this controller for designs requiring dual-slot support in PCI or PCI-X environments. It is suitable for systems needing precise current limiting and fault handling via SMBus. Consider the 48-pin TQFP footprint for PCB layout constraints. Evaluate thermal performance requirements given the integrated thermal shutdown feature. Ensure compatibility with N-channel external FETs for the power path.
