MIC2583-JYQS-TR

Hot Swap Controllers Overview

The MIC2583-JYQS-TR is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed to facilitate the safe insertion and removal of boards into live system backplanes. The device controls an external N-Channel MOSFET to manage inrush current and output voltage slew rate, preventing power supply disturbances. It features a circuit breaker function that latches the output off if current limits are exceeded for a set duration. The component operates within a supply voltage range of 2.3V to 13.2V and supports an operating temperature range from -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management via external N-Channel MOSFET gate drive.
• Integrates a programmable circuit breaker function that latches the output MOSFET off upon sustained overcurrent conditions.
• Includes undervoltage lockout (UVLO) and fault timeout protection mechanisms for robust operation in critical power environments.

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix JYQS against the official Microchip datasheet to confirm package type and temperature grade. Confirm availability status as distribution channels may list obsolete or discontinued variants. Ensure the ordering part number matches the required RoHS compliance and moisture sensitivity level specifications for your assembly process.

Hot Swap Controllers Selection Notes

Select this component when single-channel hot swap protection is required for positive voltage rails up to 13.2V. It is suitable for applications needing precise control over board insertion currents without internal switching elements. Compare with the MIC2582 if an 8-pin package is preferred instead of the 16-pin QSOP format. Ensure the external MOSFET selection aligns with the controller's gate drive capabilities.

Hot Swap Controllers Part Context

This part belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. The MIC2583 variant specifically utilizes a 16-pin QSOP package, distinguishing it from the 8-pin SOIC version found in the MIC2582 series. Both devices share similar functional architectures for managing power delivery during board insertion events.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a pin-compatible alternative in terms of functionality but differs in package configuration (8-SOIC vs 16-QSOP). Verify PCB footprint compatibility before substitution. Other generic hot swap controllers may lack the specific latch-off circuit breaker characteristics documented for this Microchip series.
