MIC2583R-MBQS

Hot Swap Controllers Overview

The MIC2583R-MBQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed for safe board insertion into live backplanes by controlling an external N-Channel MOSFET. The device operates within a supply voltage range of 2.3V to 13.2V and draws a supply current of 1.5 mA. It features programmable fault timeout, slew rate control, and under-voltage lockout (UVLO). The component is housed in a 16-QSOP surface-mount package with a width of 3.90mm. It supports an operating temperature range from -40°C to 85°C and includes automatic retry functionality.

Hot Swap Controllers Feature Summary

• Provides inrush current limiting and output voltage slew rate control via external N-Channel MOSFET gate drive.
• Includes circuit breaker function that latches the output MOSFET off if current limit threshold is exceeded for a determined period.
• Features programmable fault timeout, slew rate, and under-voltage lockout (UVLO) capabilities.

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh, critical power supply environments
• General-purpose hot swap applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'MBQS' against current manufacturer documentation, as this variant may be discontinued or superseded. Confirm RoHS compliance status, as older MBQS variants may not meet current REACH or RoHS3 standards compared to newer MYQS equivalents. Ensure the 16-QSOP package availability aligns with current manufacturing data sheets before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when a single-channel hot swap solution with programmable protection thresholds is required. It is suitable for designs needing precise control over turn-on slew rates and fault timeouts. Consider the 16-pin QSOP package constraints for PCB layout. Verify compatibility with the intended external N-Channel MOSFET gate drive requirements and ensure the 2.3V to 13.2V supply range matches the system architecture.

Hot Swap Controllers Part Context

The MIC2583 belongs to the MIC2582/MIC2583 family of single-channel positive voltage hot swap controllers. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 uses a 16-pin QSOP package to accommodate additional programmable features. This family allows designers to protect sensitive electronics during hot insertion events without requiring internal switches, relying instead on external MOSFETs for power handling.

Hot Swap Controllers Replacement Considerations

MIC2583R-MYQS is listed as a direct replacement for the MIC2583R-MBQS. Verify that the MYQS suffix indicates updated packaging or compliance standards while maintaining identical electrical functionality and pinout compatibility.
