MIC2583-MYQS

Hot Swap Controllers Overview

The MIC2583-MYQS-TR is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed for safe board insertion into live system backplanes. The device operates within a supply voltage range of 2.3V to 13.2V and draws a supply current of 1.5 mA. It functions in an industrial temperature range from -40°C to +85°C. The component is housed in a 16-pin QSOP package with a width of 3.90mm. It lacks an internal switch, requiring an external N-Channel MOSFET for gate drive control.

Hot Swap Controllers Feature Summary

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

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix MYQS corresponds to the 16-QSOP package variant when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation, noting potential variations between standard and military-grade (JBQS) versions. Ensure the procurement channel provides official datasheets matching the MIC2583 series specifications to avoid counterfeit components.

Hot Swap Controllers Selection Notes

Select this component for applications requiring single-channel hot swap protection without an integrated switch. Compare against the MIC2582 if an 8-pin SOIC package is preferred for space-constrained designs. Consider the MIC2583-JBQSTR for extended environmental qualification requirements. Verify external MOSFET compatibility with the controller's gate drive capabilities.

Hot Swap Controllers Part Context

The MIC2583 belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. It serves as the 16-pin QSOP counterpart to the 8-pin MIC2582. Both devices share identical functional characteristics for managing power insertion events. The family is designed to protect downstream circuits during board insertion or removal in live systems.
