MIC2583R-LBQS

Hot Swap Controllers Overview

The MIC2583R-LBQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. Designed for safe board insertion into live backplanes, it controls an external N-Channel MOSFET to manage inrush current and output voltage slew rate. The device features programmable fault timeout, UVLO, and slew rate settings. It operates within a supply voltage range of 2.3V to 13.2V and draws 1.5mA of supply current. The component supports automatic retry functionality and is housed in a 16-QSOP package suitable for surface mount applications.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management via external N-Channel MOSFET gate drive
• Integrates circuit breaker function that latches the output off if current limit threshold is exceeded for a set duration
• Supports automatic retry feature to restore power after fault conditions clear

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Inrush current limiting in critical power supply environments
• Output voltage slew rate control for harsh operating conditions

Hot Swap Controllers Procurement Notes

Verify the specific suffix LBQS against official Microchip documentation to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required package type and temperature range for your design. Cross-reference ordering information with authorized distributors to confirm availability and lead times. Confirm RoHS compliance status prior to final procurement decisions.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against overcurrent events. The MIC2583R-LBQS is appropriate for applications needing adjustable fault timeouts and automatic recovery mechanisms. Consider the external MOSFET requirements and available programming options for UVLO and slew rate settings during the selection process.

Hot Swap Controllers Part Context

This component belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 variants, including the LBQS suffix, are designed for 16-pin QSOP packages. This family provides general-purpose hot swap protection solutions for managing power delivery in complex electronic systems.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a functional alternative in the same family but utilizes an 8-pin SOIC package instead of the 16-pin QSOP form factor. Verify pin-to-pin compatibility and package dimensions before substituting. No other direct public substitute part numbers are confirmed for this specific model.
