MIC2583R-KYQS-TR

Hot Swap Controllers Overview

The MIC2583R-KYQS-TR 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, along with automatic retry capabilities. It operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. The component is housed in a 16-pin QSOP package and supports surface mount installation across an industrial temperature range of -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 circuit breaker functionality that latches the output off if current limit thresholds are exceeded for a set duration.
• Supports automatic retry mechanisms following fault conditions to enhance system availability.

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 applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'KYQS' against official Microchip documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage parameters before integration. Confirm RoHS compliance status as indicated in the latest datasheet revisions.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against overcurrent events. It is suitable for applications needing adjustable fault timeouts and automatic recovery features. Consider the external MOSFET requirements and available programming pins for customizing threshold levels.

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 offers additional functionality or pinout options in a 16-pin QSOP format. Both devices serve similar purposes in managing power delivery during board insertion.

Hot Swap Controllers Replacement Considerations

The MIC2582 series serves as a functional alternative for single-channel hot swap control, though it utilizes an 8-pin SOIC package instead of the 16-pin QSOP form factor. Verify pinout compatibility and feature parity before substitution.
