The MAX5924BEUB+T is a hot swap controller that allows a system to safely hot-swap a power supply or board. It operates as a bi-directional MOSFET controller, providing current control in both directions. The MAX5924BEUB+T operates from a supply voltage of 4.5V to 60V, and ensures a low on-resistance MOSFET with a current range of up to 10A. This makes the MAX5924BEUB+T suitable for hot-swapping power supplies or boards due to its continuous over-temperature protection.

Features

The MAX5924BEUB+T features designed to aid in hot-swapping applications:

• Integrated foldback protection limits inrush current and power dissipation on insertion.
• Integrated thermal shutoff ensures safe operation at high current.
• Active power-good output monitors MOSFET switching and load current.
• Adjustable soft-start, foldback, and current-limit functions.
• Adjustable power-good delay.

Application Field

The MAX5924BEUB+T is ideal for hot-swapping applications such as power supplies or boards. It offers a highly efficient solution when hot-swapping high-current loads, as it can handle up to 10A and can operate over a 4.5V to 60V input voltage range. This makes it ideal for high-current loads, such as those found in telecommunications systems and industrial equipment.

Working Principle

The MAX5924BEUB+T operates as a bi-directional MOSFET controller, providing current control in both directions. It features an adjustable current-limit threshold, allowing users to set a desired current limit. Additionally, it features an adjustable soft-start and foldback functions, allowing users to customize the startup behavior. The integrated over-temperature protection ensures that the MOSFET does not overheat even at high current. Lastly, the integrated power-good output allows users to monitor the MOSFET switching and the load current, ensuring that the system is operating correctly.

Conclusion

The MAX5924BEUB+T is an ideal hot-swap controller for applications requiring high current and wide input voltage range.
