MIC2590B-2BTQ-TR

Hot Swap Controllers Overview

The MIC2590B-2BTQ-TR is a dual-channel hot-swap voltage controller designed for PCI and PCI-X compliant systems. It supports supply voltages of 3.3V, 5V, and ±12V. The device integrates programmable current limit, fault timeout, and slew rate controls to manage power distribution safely during insertion and removal. Packaged in a 48-TQFP (7x7 mm) case, it operates with a maximum output current capability of 500mA per channel and includes an internal 100mA regulator for control logic.

Hot Swap Controllers Feature Summary

• Dual-channel architecture supporting independent hot-plug operations for PCI/PCI-X applications
• Programmable parameters including current limit thresholds, fault timeouts, and voltage slew rates
• Integrated protection mechanisms against overcurrent and thermal events during system transitions

Hot Swap Controllers Applications

• PCI bus hot-plug controllers
• PCI-X compliant system power distribution
• Server backplane power management

Hot Swap Controllers Procurement Notes

Verify the specific suffix '2BTQ' confirms the 48-TQFP package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official Microchip documentation as availability may vary by production batch. Ensure the component matches the exact part number to avoid pinout or functional mismatches with similar variants in the MIC2590 family.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring independent control of two high-current rails for hot-pluggable peripherals. It is suitable for applications needing precise regulation of inrush current and soft-start characteristics. Verify that the required supply voltages align with the supported 3.3V, 5V, and ±12V inputs before integration into the power architecture.

Hot Swap Controllers Part Context

This part belongs to the MIC2590B series of hot-swap controllers manufactured by Microchip Technology. It serves as a specialized power management IC for peripheral interconnect standards. The device replaces discrete protection circuits by integrating sensing and control logic into a single compact package, simplifying board layout for high-density server and workstation designs.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other MIC2590B variants with compatible packages. Verify pin compatibility and electrical specifications before swapping. Generic hot-swap controllers may lack the specific PCI compliance features required for this application.
