The MIC2582-JBM from Microchip Technology is a robust, high-performance Hot Swap Controller IC designed to enable safe insertion and removal of boards in live backplane systems. This integrated circuit ensures the reliable operation of servers, routers, and other sophisticated electronic equipment by managing the inrush current during system hot plugging.

Key Features

• Programmable Current Limit: The MIC2582-JBM allows designers to set a precise current limit threshold, ensuring protection against excessive currents that could potentially damage the system.
• Adjustable Overcurrent Timeout: This feature provides a time delay before the controller shuts down the output, which helps to distinguish between transient overcurrent conditions and true fault states.
• Undervoltage Lockout (UVLO): The UVLO feature ensures that the IC operates only when the supply voltage is within an acceptable range, protecting the system from low-voltage conditions.
• Thermal Shutdown: To prevent overheating, the MIC2582-JBM includes a thermal shutdown mechanism that turns off the output when the junction temperature exceeds safe limits.
• Status Flag Output: The IC provides a status flag output that can be used to signal the system about the operational status, such as the occurrence of an overcurrent or thermal shutdown event.

Applications

The MIC2582-JBM is suitable for a wide range of applications where hot swap capability is a necessity. This includes:

• Server and Storage Systems
• Network Routers and Switches
• Base Stations
• Industrial Computers
• High-Availability Systems
