MIC2580A-1.0YTS

Hot Swap Controllers Overview

The MIC2580A-1.0YTS is a four-channel hot-swap controller and switching regulator designed for CompactPCI and PCI applications. It operates within an input voltage range of 3.1 V to 12.6 V and supports standard supply voltages of 3.3 V, 5 V, and 12 V. The device integrates both internal high-side and low-side switches for comprehensive power management. It functions in an operating temperature range from -40°C to +85°C and is housed in a 24-pin TSSOP package.

Hot Swap Controllers Feature Summary

• Integrates four independent channels with internal high-side and low-side switches for precise load control
• Provides overvoltage protection thresholds to safeguard connected circuitry during fault conditions
• Supports hot-swap operations allowing safe insertion and removal of cards under power
• Designed specifically for compliance with CompactPCI and PCI bus power requirements

Hot Swap Controllers Applications

• CompactPCI system backplanes
• PCI bus interface modules
• Hot-swappable peripheral cards
• Industrial control systems requiring redundant power paths

Hot Swap Controllers Procurement Notes

Verify the exact suffix against official Microchip documentation to confirm pinout and electrical specifications. Confirm current product status as listings may indicate obsolete status. Ensure the package type matches the required PCB footprint. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring multi-channel power sequencing and protection for PCI or CompactPCI architectures. Evaluate the input voltage range against the system's available rails. Consider the thermal performance of the TSSOP package relative to the expected load currents. Verify that the integrated switch capabilities meet the specific surge and steady-state current demands of the application.
