Microchip Technology's MIC2583R-JYQS-TR Hot Swap Controller

The MIC2583R-JYQS-TR is a state-of-the-art hot swap controller from Microchip Technology, designed to provide a robust power management solution for systems that require hot insertion and removal of circuit cards. This integrated circuit ensures the safe insertion of cards into live backplanes without causing glitches or disruptions to the existing system power rail.

Key Features

• Programmable Current Limit: The MIC2583R-JYQS-TR offers a programmable current limit feature, which allows for precise control over the maximum amount of current that can be drawn by the card. This helps to prevent damage to the card or the power supply due to overcurrent conditions.
• Adjustable Overcurrent Timeout: The device includes an adjustable overcurrent timeout function, providing additional protection by setting a specific time period for which an overcurrent condition is allowed before a fault is declared and the load is disconnected.
• Undervoltage Lockout (UVLO): With an undervoltage lockout feature, the controller ensures that the system operates only when the supply voltage is within the acceptable range, protecting the system from low-voltage conditions.
• Thermal Shutdown: An integrated thermal shutdown mechanism protects the device from overheating, enhancing the reliability and longevity of the system.
• Charge Pump: The built-in charge pump allows for the control of external N-channel MOSFETs, which can be used to smoothly ramp up the voltage to the card during insertion, minimizing inrush current and system disturbances.
• Status Flag: A status flag output is provided to indicate power good, fault conditions, or to signal that the card has been safely inserted or removed.

Applications

The MIC2583R-JYQS-TR is ideal for a variety of applications where hot swap capability is essential, such as telecom and datacom systems, servers, RAID systems, and industrial computers. Its robust design ensures that it can meet the stringent requirements of high-availability systems, providing reliable performance even in challenging environments.

Packaging and Availability

This hot swap controller is available in a compact, surface-mount QFN package, making it suitable for space-constrained applications. The MIC2583R-JYQS-TR is also offered in tape and reel packaging, facilitating efficient handling and manufacturing processes for high-volume production.

With its advanced features and reliable performance, the MIC2583R-JYQS-TR from Microchip Technology represents a comprehensive solution for power management in hot-swappable systems.
