MIC25383R-JBQS

Hot Swap Controllers Overview

The MIC25383R-JBQS is a single-channel positive voltage hot swap controller designed for safe board insertion into live system backplanes. It operates within an input voltage range of 2.3V to 13.2V and supports a maximum output current capability defined by external MOSFET selection. The device features adjustable thresholds, under-voltage lockout (UVLO), and power-on reset functions. Packaged in a 16-pin QSOP, it provides inrush current limiting and output voltage slew rate control. The operational junction temperature range spans from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management during board insertion.
• Integrates circuit breaker functionality that latches the output off if current limits are exceeded.
• Includes under-voltage lockout (UVLO) and power-on reset protection mechanisms.

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh critical power supply environments requiring controlled power-up sequences
• Single channel positive voltage hot swap applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'JBQS' corresponds to the 16-pin QSOP package variant when sourcing. Confirm that the 'R' designation aligns with required reel packaging specifications. Ensure the selected component matches the single-channel configuration and positive voltage operation requirements. Cross-reference the manufacturer's latest datasheet to confirm active status and pin compatibility with existing designs.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring safe hot-swap capabilities for single-channel positive voltage rails. It is suitable for applications needing precise inrush current limiting and voltage slew rate control. Consider the external N-Channel MOSFET requirements for gate drive and current handling. Evaluate the need for latch-off circuit breaker protection against over-current conditions in critical power environments.

Hot Swap Controllers Part Context

This component belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers manufactured by Microchip Technology. These devices are engineered to protect system backplanes and inserted boards during power-up events. The family offers flexibility through external component control of MOSFET gate drive, enabling customization of power-up characteristics for various industrial and commercial applications.

Hot Swap Controllers Replacement Considerations

The MIC2582 serves as a pin-compatible alternative in an 8-pin SOIC package for space-constrained designs. Verify functional equivalence regarding voltage ranges and protection features before substitution. Ensure the replacement part number matches the required package type and electrical specifications for the specific application.
