MIC2583-JYQS

Hot Swap Controllers Overview

The MIC2583-JYQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed to allow the safe insertion of boards into live system backplanes. The device controls an external N-Channel MOSFET to provide inrush current limiting and output voltage slew rate control. It features a circuit breaker function that latches the output off if the current limit threshold is exceeded for a determined period. The component operates within a supply voltage range of 2.3V to 13.2V and is available in a 16-pin QSOP package.

Hot Swap Controllers Feature Summary

• Provides inrush current limiting and output voltage slew rate control via external N-Channel MOSFET gate drive
• Includes a circuit breaker function that latches the output MOSFET off upon sustained overcurrent conditions
• Supports safe board insertion into live system backplanes in harsh power supply environments

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 sensitive loads

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'JYQS' against the official Microchip datasheet to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with the required 16-pin QSOP footprint and check for any recent Product Change Notices (PCN) regarding packaging or manufacturing site changes before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when a single-channel hot swap solution is required for positive voltage applications. It is suitable for systems needing programmable fault timeout and undervoltage lockout. Consider the 16-pin QSOP package constraints and the need for an external N-Channel MOSFET for current handling capabilities compared to integrated switch solutions.

Hot Swap Controllers Part Context

The MIC2583 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 pinout options for enhanced functionality or ease of layout in larger form factors. Both share similar core control logic for safe hot swapping.

Hot Swap Controllers FAQ

Does the MIC2583-JYQS include an internal power switch?

No, the MIC2583 is a controller that requires an external N-Channel MOSFET to handle the load current.

What protection features are included in the MIC2583?

It includes inrush current limiting, output voltage slew rate control, undervoltage lockout (UVLO), and a latch-off circuit breaker function for overcurrent events.
