MIC2583R-JYQS

Hot Swap Controllers Overview

The MIC2583R-JYQS is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It is designed to facilitate the safe insertion of boards into live system backplanes. The device controls an external N-Channel MOSFET to provide inrush current limiting and output voltage slew rate control. Key electrical parameters include a supply voltage range of 2.3V to 13.2V, a supply current of 1.5 mA, and an operating temperature range of -40°C to 85°C. It features programmable fault timeout, slew rate, and UVLO, along with automatic retry capabilities.

Hot Swap Controllers Feature Summary

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

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh power supply environments requiring inrush current management
• Critical power supply applications needing controlled voltage slew rates

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'JYQS' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with the required external N-Channel MOSFET gate drive specifications. Confirm RoHS compliance status as indicated in the latest datasheet revision. Check for any recent Product Change Notifications (PCN) regarding packaging or manufacturing site changes.

Hot Swap Controllers Selection Notes

Select this component when a single-channel hot swap solution is required for positive voltage systems. It is suitable for applications needing precise control over inrush current and voltage ramp-up times. Consider the 16-pin QSOP package constraints and the need for an external MOSFET. Evaluate if the programmable protection features meet the specific fault tolerance requirements of the target system.

Hot Swap Controllers Part Context

The MIC2583R-JYQS belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. This family is designed to protect circuits during board insertion by controlling the gate drive of an external N-Channel MOSFET. The MIC2583 variant specifically utilizes a 16-pin QSOP package, distinguishing it from the 8-pin SOIC version found in the MIC2582 series.

Hot Swap Controllers FAQ

Does the MIC2583R-JYQS contain an internal switch?

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

What protection features are included in the MIC2583R-JYQS?

It includes inrush current limiting, output voltage slew rate control, under-voltage lockout (UVLO), and a circuit breaker function that latches off upon prolonged overcurrent conditions.
