Hot Swap Controllers datasheet and documents for MIC2580-1.0BTSTR
Hot Swap Controllers Overview
The MIC2580-1.0BTSTR is a hot-swap controller designed for PCI and CompactPCI systems, manufactured by Micrel Inc. It supports power control for +3.3V, +5V, and ±12V rails. The device features circuit breaker functionality with foldback current limiting to protect the system during fault conditions. It includes under-voltage and over-current diagnostic outputs with spike filtering. The component operates within standard industrial temperature ranges and is housed in a surface-mount package suitable for high-density board layouts.
Hot Swap Controllers Feature Summary
- Integrated circuit breaker protection with foldback current limiting for robust fault handling
- Supports simultaneous control of +3.3V, +5V, and ±12V power rails
- Diagnostic outputs for under-voltage and over-current events with spike filtering
Hot Swap Controllers Applications
- PCI hot-plug systems
- CompactPCI hot-plug systems
- Server backplane power management
Hot Swap Controllers Procurement Notes
Verify the specific suffix '1.0BTSTR' against official Microchip documentation to confirm threshold settings and package type. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm RoHS compliance status for the specific manufacturing lot. Cross-reference pinouts with the latest datasheet revision to avoid integration errors.
Hot Swap Controllers Selection Notes
Select this component when designing systems requiring controlled insertion of PCI or CompactPCI cards. It is suitable for applications needing precise current limiting and diagnostic feedback. Consider the supported voltage rails (+3.3V, +5V, ±12V) to ensure alignment with system power architecture. Evaluate the need for foldback current limiting versus fixed limits based on load characteristics.
Hot Swap Controllers Part Context
The MIC2580 series belongs to Micrel's portfolio of power management solutions for expansion bus systems. Originally developed by Micrel, now part of Microchip Technology, these controllers address the challenges of safe hot-swapping in legacy and industrial computing environments. The family provides reliable power sequencing and protection for multi-rail architectures common in server and communication hardware.
Hot Swap Controllers Replacement Considerations
Check for updated Microchip equivalents if Micrel legacy parts are discontinued. Verify functional compatibility regarding threshold voltages and package dimensions before substitution.
