MIC2583-KBQS

Hot Swap Controllers Overview

The MIC2583-KBQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It enables safe insertion of boards into live system backplanes by controlling an external N-Channel MOSFET. The device provides inrush current limiting and output voltage slew rate control. Key programmable features include fault timeout, UVLO, and slew rate adjustment. It operates within a supply voltage range of 2.3V to 13.2V and draws 1.5 mA of supply current. The component is housed in a 16-QSOP package and functions across a temperature range of -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Provides inrush current limiting and output voltage slew rate control for safe board insertion into live backplanes.
• Features a circuit breaker function that latches the output MOSFET off if the current limit threshold is exceeded for a determined period.
• Offers programmable fault timeout, under-voltage lockout (UVLO), and slew rate settings.

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 component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment prior to installation. Check datasheet revisions for any updates to electrical characteristics or thermal specifications. Ensure compatibility with external N-Channel MOSFET gate drive requirements. Validate operating temperature ranges against application environmental conditions.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise control over power-up sequences and protection against overcurrent events. Consider the 16-pin QSOP package for space-constrained designs. Evaluate the need for programmable fault timeouts and slew rates based on system sensitivity. Ensure the external MOSFET selection aligns with the controller's gate drive capabilities and current limits.

Hot Swap Controllers Part Context

The MIC2583 belongs to a family of single-channel hot swap controllers designed for harsh power supply environments. It complements similar models like the MIC2582, which offers an 8-pin SOIC package. These devices are part of Microchip's broader portfolio of power management solutions aimed at enhancing system reliability during board insertion and removal.

Hot Swap Controllers Replacement Considerations

MIC2583-KYQS-TR is listed as a direct substitute. Verify pinout compatibility and electrical parameter equivalence before substitution. Confirm that the alternative package type meets mechanical constraints of the existing design.
