MIC2583-LYQS

Hot Swap Controllers Overview

The MIC2583-LYQS 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 operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. It functions in conjunction with an external N-Channel MOSFET to manage inrush current and control output voltage slew rates. The component is housed in a 16-pin QSOP package and supports an operating temperature range from -40°C to +85°C.

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 limits are exceeded for a set duration.
• Features programmable fault timeout, UVLO, and slew rate settings via external components.

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix LYQS against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with the required 16-QSOP footprint. Confirm RoHS compliance status as per the latest datasheet revision. Check for any recent PCN updates regarding packaging or manufacturing site changes before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this controller when a single-channel solution is required for positive voltage hot swap applications. It is suitable for systems needing adjustable fault protection and slew rate control without an integrated switch. Consider the 16-pin QSOP package constraints and the need for an external N-Channel MOSFET during PCB layout and component selection.

Hot Swap Controllers Part Context

The MIC2583 belongs to a family of single-channel hot swap controllers that includes the MIC2582. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 variant uses a 16-pin QSOP package, offering additional pinout options for enhanced configuration capabilities. Both devices share similar core functionalities for protecting loads during insertion and removal.

Hot Swap Controllers FAQ

Does the MIC2583-LYQS include an internal switch?

No, the MIC2583-LYQS does not contain an internal switch. It requires an external N-Channel MOSFET to handle the load current.

What is the function of the circuit breaker feature?

The circuit breaker function monitors the current limit threshold and will latch the output MOSFET off if the threshold is exceeded for a determined period, providing overcurrent protection.
