MIC2583R-JBQS

Hot Swap Controllers Overview

The MIC2583R-JBQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed to facilitate the safe insertion and removal of boards into live system backplanes. The device controls an external N-Channel MOSFET to manage inrush current and output voltage slew rate, preventing bus disturbances. Key electrical parameters include a supply voltage range of 2.3V to 13.2V and a supply current of 1.5 mA. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin QSOP package.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management for external N-Channel MOSFETs
• Includes circuit breaker functionality that latches the output off if current limit thresholds are exceeded for a set duration
• Features programmable fault timeout, UVLO, and automatic retry capabilities

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Power supply management in harsh environments
• Critical power supply applications requiring surge protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix JBQS against the official Microchip datasheet to confirm pinout and functional compatibility with existing designs. Ensure the component meets RoHS3 compliance requirements as specified in the manufacturer's documentation. Confirm the 16-QSOP package dimensions match the PCB footprint specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when designing systems that require precise control over power-up sequences and surge currents. It is suitable for applications needing a single channel of hot swap protection without an integrated switch. Consider the external MOSFET selection carefully to ensure it matches the controller's gate drive capabilities and current handling 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 uses a 16-pin QSOP package, offering additional pin access for configuration. Both devices share similar core functionalities for protecting system buses during board insertion.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a pin-compatible alternative in terms of function but differs in package (8-SOIC vs 16-QSOP). Verify mechanical fit and pin assignment differences before substituting. No other direct public substitutes are confirmed.
