MIC2583-LYQS-TR

Hot Swap Controllers Overview

The MIC2583-LYQS-TR is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. Designed for safe board insertion into live system 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 with a typical supply current of 1.5 mA. The component is housed in a 16-QSOP package 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.
• Includes circuit breaker functionality that latches the output MOSFET off if the current limit threshold is exceeded for a determined period.
• Features programmable parameters including fault timeout, voltage slew rate, and under-voltage lockout (UVLO) thresholds.

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh power supply environments requiring inrush current control
• Critical power supply systems needing output voltage slew rate regulation

Hot Swap Controllers Procurement Notes

Verify the specific suffix LYQS against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing BOM requirements for 16-pin QSOP packaging. Confirm RoHS compliance status as per the latest datasheet revision. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against overcurrent conditions. It is suitable for applications where internal switches are insufficient or external high-current handling is needed. Consider the programmable nature of the fault timeout and slew rate for customizing protection thresholds to match specific load characteristics.

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 variant uses a 16-pin QSOP package, offering additional pinout options for enhanced feature accessibility. Both devices share similar core functionalities for managing positive voltage hot swap operations.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a functional alternative in the same family but differs in package configuration (8-SOIC vs. 16-QSOP). Verify pin-to-pin compatibility and footprint dimensions before substitution. Other Micrel/Microchip hot swap controllers may offer different channel counts or voltage ratings.
