MIC2583R-KBQS

Hot Swap Controllers Overview

The MIC2583R-KBQS 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 and draws 1.5mA of supply current. The component supports automatic retry functionality and functions as a circuit breaker by latching the output off if the current limit threshold is exceeded for a determined period.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management for safe hot insertion
• Integrates a circuit breaker function that latches the output MOSFET off upon sustained overcurrent conditions
• Supports automatic retry mechanisms to restore power after transient fault events

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 operational conditions

Hot Swap Controllers Procurement Notes

Verify the specific suffix KBQS against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required 16-pin QSOP form factor. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Cross-reference the ordering part number with the manufacturer's latest datasheet to avoid discrepancies in pinout or electrical characteristics.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against thermal runaway during hot swap operations. It is suitable for applications needing adjustable fault timeouts and under-voltage lockout thresholds. Consider the external N-Channel MOSFET requirements for gate drive compatibility. Evaluate the need for automatic retry features versus latch-off behavior based on system reliability requirements.

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 typically employs a 16-pin QSOP package, offering additional pin configurations for enhanced feature accessibility. The R suffix generally indicates a specific tape and reel packaging option for automated assembly processes.
