Maxim Integrated's MAX5955BUEE+ Hot-Swap Controller

The MAX5955BUEE+ from Maxim Integrated is a sophisticated hot-swap controller designed to enable safe insertion and removal of circuit boards from a live backplane. This component is particularly suited for use in network servers, storage systems, and telecommunications equipment where system uptime and reliability are of paramount importance.

This hot-swap controller operates from a supply voltage ranging from 9V to 80V, making it versatile for various applications with different power requirements. The MAX5955BUEE+ integrates a variety of features to ensure the protection of both the electronic system and the user during the hot-swap process.

Key Features

• Adjustable Overcurrent Protection: The device comes with an adjustable current limit to prevent damage due to overcurrent conditions. This feature ensures that the system remains stable and protected even under fault conditions.
• Undervoltage Lockout (UVLO): The MAX5955BUEE+ includes an undervoltage lockout function that disables the external MOSFET when the input voltage drops below a certain threshold, preventing malfunction due to insufficient power.
• Programmable Startup Time: Users can program the startup time, allowing for controlled inrush current during board insertion. This gradual power-up sequence helps to minimize any disturbances to the existing system.
• Thermal Shutdown: The device features a thermal shutdown mechanism that protects against overheating, further enhancing the safety of the system during operation.

Applications

• Network Routers and Switches
• Storage Systems
• Telecommunications Equipment
• High-Availability Systems
• Server and Blade Systems

The MAX5955BUEE+ is available in a 16-lead TSSOP package, which is suitable for compact PCB designs. Maxim Integrated's commitment to quality and reliability is evident in the design and functionality of this hot-swap controller, making it an excellent choice for critical systems where continuous operation is essential. By utilizing the MAX5955BUEE+, system designers can ensure that their products are capable of handling the rigors of hot-swapping without compromising performance or safety.
