MIC2592B-2YTQ-TR

Hot Swap Controllers Overview

The MIC2592B-2YTQ-TR is a dual-slot PCI Express hot-swap power controller manufactured by Microchip Technology. It manages power sequencing and protection for two PCIe slots in a single TQFP-48 package. The device supports independent control of each slot, including soft-start, over-current, and over-voltage protection. It operates with negative voltage supplies for high-side N-channel MOSFETs. The component is designated as Not Recommended for New Designs (NRND).

Hot Swap Controllers Feature Summary

• Dual-slot architecture enabling independent management of two PCI Express expansion slots.
• Integrated protection mechanisms including over-current, over-voltage, and thermal shutdown.
• Supports negative voltage operation for driving high-side N-channel MOSFET switches.

Hot Swap Controllers Applications

• PCI Express server backplanes requiring hot-plug capability.
• Industrial computer systems with modular expansion card support.
• Telecommunications equipment utilizing standard PCIe form factors.

Hot Swap Controllers Procurement Notes

Verify the NRND status before integration into new hardware designs. Confirm that the TQFP-48 package dimensions align with the target PCB footprint. Ensure moisture sensitivity handling protocols are followed during assembly to prevent package damage. Review the latest datasheet for any updates to electrical characteristics or recommended operating conditions.

Hot Swap Controllers Selection Notes

Select this component only if legacy compatibility with existing dual-slot PCIe designs is required. Evaluate alternative controllers if new product development is underway due to the discontinued status. Ensure the system design accommodates the specific gate drive requirements for external N-channel MOSFETs.

Hot Swap Controllers Part Context

This part belongs to the MIC2592 family of hot-swap controllers. It is functionally related to the MIC2590 and MIC2593 series but offers specific dual-slot capabilities. The manufacturer has transitioned this specific part number to end-of-life status, influencing long-term supply chain planning for maintenance projects.

Hot Swap Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology directly for current portfolio recommendations or equivalent replacement strategies.
