MIC2580-1.6BTS

Hot Swap Controllers Overview

The MIC2580-1.6BTS is a high-side power switch manufactured by Micrel, now part of Microchip Technology. It is designed for low-loss DC power switching and advanced configuration and power interface (ACPI) applications. The device integrates precision current limiting and soft-start capabilities to manage load currents and minimize inrush current upon enablement. It features thermal shutdown protection and an open-drain fault flag output to signal current-limiting or thermal events to a local controller. The component supports both active-high and active-low enable signals compatible with 3V and 5V logic levels.

Hot Swap Controllers Feature Summary

• Integrates adjustable current-limit and soft-start circuitry to control inrush current
• Provides thermal shutdown protection with an open-drain fault flag output
• Features reverse current flow blocking capability
• Supports active-high and active-low enable signals compatible with standard logic levels

Hot Swap Controllers Applications

• Low-loss DC power switching systems
• Advanced Configuration and Power Interface (ACPI) implementations
• USB power management applications

Hot Swap Controllers Procurement Notes

Verify the manufacturer designation carefully, as Micrel was acquired by Microchip Technology. Ensure the specific suffix matches the required enable polarity and package type. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the datasheet revision to ensure compatibility with your system's voltage and current requirements.

Hot Swap Controllers Selection Notes

Select this component when a cost-effective, highly integrated high-side switch is needed for ACPI or USB applications. Consider the MIC2580 series for its low on-resistance and minimal external component requirements. Evaluate the specific current limit settings and enable logic polarity against your system design constraints before finalizing the selection.

Hot Swap Controllers Part Context

This component belongs to the MIC2545A/MIC2549A family of high-side switches. These devices are optimized for applications requiring robust load current management and fault protection. The family offers various package options including DIP, SOIC, and TSSOP to suit different board space and thermal requirements.

Hot Swap Controllers Replacement Considerations

Direct substitutes within the same family include MIC2545A and MIC2549A variants. Verify pinout compatibility and electrical specifications such as on-resistance and current limit ranges. Check for equivalent enable logic polarity and package dimensions to ensure mechanical fit.
