MIC2583-JBQS

Hot Swap Controllers Overview

The MIC2583-JBQS 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 a circuit breaker function that latches the output off if current limits are exceeded. It operates within a supply voltage range of 2.3V to 13.2V and supports a supply current of 1.5 mA. The component is housed in a 16-pin QSOP package and functions across a 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.
• Includes a programmable circuit breaker function that latches the output MOSFET off upon prolonged overcurrent conditions.
• Offers adjustable fault timeout, UVLO, and slew rate settings for customizable protection profiles.

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 'JBQS' against official Microchip documentation to confirm exact package dimensions and thermal characteristics. Ensure compatibility with the required 16-QSOP footprint during PCB layout. Confirm RoHS compliance status for the specific manufacturing batch prior to integration.

Hot Swap Controllers Selection Notes

Select this controller when single-channel hot swap protection is required for positive voltage rails. It is suitable for designs needing precise control over turn-on slew rates and robust overcurrent latching. Consider the 16-pin QSOP package constraints and the necessity for an external N-Channel MOSFET for high-current handling.

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 provides additional functionality or pinout options in a 16-pin QSOP format. Both devices share similar core protection mechanisms but differ in physical packaging and potentially available feature sets.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a related single-channel alternative but utilizes an 8-pin SOIC package rather than the 16-pin QSOP form factor. Verify pinout compatibility and package dimensions before substituting. No other direct public substitutes are confirmed for this specific part number.
