MIC2582-JBM

Hot Swap Controllers Overview

The MIC2582-JBM is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. It operates within a supply voltage range of 2.3V to 13.2V and draws a supply current of 1.5 mA. The device is housed in an 8-SOIC package with dimensions of 0.154 inches (3.90mm) width. It supports surface mount installation and functions across a temperature range of -40°C to 85°C. Key programmable features include slew rate control and under-voltage lockout (UVLO). The component includes latch fault protection and is designed for general applications.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management for safe board insertion into live backplanes.
• Features an electronic circuit breaker function that latches the output MOSFET off when current limits are exceeded for a set duration.
• Includes under-voltage lockout (UVLO) protection and programmable output under-voltage detection capabilities.

Hot Swap Controllers Applications

• RAID systems
• Base stations
• PC board hot swap insertion and removal
• +12V backplanes
• Network switches

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'JBM' against the official Microchip datasheet to confirm exact electrical tolerances and pin compatibility, as ordering suffixes define specific performance grades. Confirm availability status, as distributor records indicate this specific variant may be discontinued or out of stock. Ensure the selected packaging format matches production requirements and check for any recent Product Change Notifications regarding manufacturing origin or material composition updates.

Hot Swap Controllers Selection Notes

Select the MIC2582-JBM for applications requiring precise control over power-up sequences without internal switching elements. This controller requires an external N-Channel MOSFET for gate drive control. Consider the 8-SOIC package constraints for PCB layout. Evaluate if the latch-fault protection aligns with system recovery strategies, as it differs from auto-restart variants like the MIC2583R. Ensure the external MOSFET selection complements the controller's current limit thresholds.

Hot Swap Controllers Part Context

The MIC2582 series serves as a general-purpose solution for protecting circuits during hot insertion events. It acts as a companion to external power switches rather than containing an integrated switch. The device ensures smooth power ramping and protects against short circuits and overcurrent conditions in critical power supply environments, maintaining system integrity during maintenance or expansion.

Hot Swap Controllers Replacement Considerations

The MIC2582-MYM is a direct functional equivalent available in the same 8-SOIC package. The MIC2583 offers similar control but includes auto-restart functionality and additional status outputs in a 16-pin QSOP package. Verify pin-to-pin compatibility before substituting with other single-channel hot swap controllers.
