MIC2583-KYQS

Hot Swap Controllers Overview

The MIC2583-KYQS 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 operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. It functions reliably across an industrial temperature range of -40°C to +85°C. The component is housed in a 16-pin QSOP package with surface mount installation.

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 circuit breaker function that latches the output MOSFET off if the current limit threshold is exceeded for a specified duration.
• Includes programmable fault timeout, UVLO, and power-on reset features for robust protection in critical power supply 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 critical systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'KYQS' against official Microchip documentation to confirm exact package dimensions and tape/reel specifications. Ensure compatibility with the required operating temperature range and supply voltage parameters before integration. Cross-reference the datasheet revision history for any recent packaging or testing changes.

Hot Swap Controllers Selection Notes

Select this controller when a single-channel solution is required for positive voltage hot swap applications. It is suitable for designs needing adjustable fault timeouts and precise slew rate control without internal switching elements. Consider the 16-pin QSOP footprint constraints and the necessity for an external N-Channel MOSFET in the schematic design.

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 specifically employs a 16-pin QSOP package to accommodate additional control pins. Both devices share identical functional capabilities for managing power insertion sequences and protecting downstream circuits from overcurrent conditions.
