MIC2583-MYQS-TR

Hot Swap Controllers Overview

The MIC2583-MYQS-TR 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 operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. It features programmable fault timeout, UVLO, and slew rate settings. 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 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.
• Supports programmable parameters including fault timeout, under-voltage lockout (UVLO), and slew rate.

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 MYQS corresponds to the 16-QSOP package variant when sourcing. Confirm RoHS compliance status as REACH information indicates potential variations. Ensure the ordering part number matches the required tape-and-reel quantity specifications provided by the distributor. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise control over power-up sequences without internal switching capabilities. It is suitable for systems where external MOSFET selection allows optimization for specific voltage and current requirements. Consider the 16-pin QSOP footprint constraints during PCB layout. Verify that the external MOSFET chosen can handle the maximum load current and voltage ratings defined by the application's power bus specifications.

Hot Swap Controllers Part Context

This part belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 variant specifically uses a 16-pin QSOP package to accommodate additional control pins. Both devices share similar functional architectures for managing high-voltage hot swap operations in server and communication infrastructure equipment.
