MIC2583R-JBQS-TR

Hot Swap Controllers Overview

The MIC2583R-JBQS-TR is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. Designed for safe board insertion into live backplanes, it controls an external N-Channel MOSFET to manage inrush current and output voltage slew rate. The device features programmable fault timeout, UVLO, and slew rate settings, along with automatic retry capabilities. It operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. 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 off if current limit thresholds are exceeded for a set duration.
• Features programmable parameters for fault timeout, undervoltage lockout (UVLO), and slew rate adjustment.

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 the specific suffix JBQS against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing BOM requirements for the 16-QSOP form factor. Confirm RoHS compliance status as per the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and sourcing channels.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise control over power-up sequences and protection against overcurrent conditions during hot insertion. It is suitable for applications needing adjustable fault timeouts and automatic retry mechanisms. Consider the external MOSFET selection carefully, as the controller relies on it for power handling. Evaluate the 16-pin QSOP package constraints against PCB layout space limitations.

Hot Swap Controllers Part Context

This component belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 variant offers additional pinouts in an 16-pin QSOP configuration, facilitating more complex programmability options. Both devices share similar core functionalities for protecting loads during insertion into energized backplanes.

Hot Swap Controllers Replacement Considerations

The MIC2582 series serves as a functional alternative for applications not requiring the additional pins or specific package footprint of the MIC2583. Verify pin-to-pin compatibility and parameter alignment before substitution. No other direct public substitute part numbers are confirmed in the provided data.
