MIC2583R-LYQS

Hot Swap Controllers Overview

The MIC2583R-LYQS 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, slew rate, and under-voltage lockout (UVLO). It operates within a supply voltage range of 2.3V to 13.2V and draws a supply current of 1.5 mA. The component is housed in a 16-pin QSOP package with a wide 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 via external N-Channel MOSFET gate drive.
• Includes circuit breaker functionality that latches the output MOSFET off if the current limit threshold is exceeded for a set duration.
• Features automatic retry capability following fault conditions.

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh power supply environments requiring inrush current control
• Critical power supply applications needing output voltage slew rate regulation

Hot Swap Controllers Procurement Notes

Verify the specific suffix LYQS against official Microchip documentation to confirm package type and compliance status. Ensure compatibility with existing BOM requirements for the 16-QSOP form factor. Confirm RoHS and REACH compliance details directly with the manufacturer or authorized distributors prior to procurement.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against overcurrent events. It is suitable for applications where internal switches are insufficient and external MOSFETs are preferred for handling higher currents or voltages. Consider the programmable features for customizing fault response times.

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 pinouts for enhanced programmability and control features.

Hot Swap Controllers Replacement Considerations

MIC2583R-MYQS is listed as a direct replacement option in distributor records.

Hot Swap Controllers FAQ

Does the MIC2583R-LYQS contain an internal switch?

No, the MIC2583R-LYQS does not have an internal switch; it requires an external N-Channel MOSFET for operation.

What protection features are included in this controller?
