The MAX5963UTL+T is a flexible, easy-to-use hot swap controller for board-level power supply sequences. It simplifies the complexity of implementing hot swap circuits, enabling designers to develop an application with minimal board space for a broad range of board power technologies. It has been widely used in a variety of fields, providing precision current regulation and shutdown control of high power applications.

MAX5963UTL+T Application Field

The MAX5963UTL+T hot swap controllers are designed to provide a high level of safety and reliability in a wide range of applications. It is widely used in data centers, telecom systems, industrial machines, network switches, and other applications that require a hot swap controller solution. It supports multiple control operations, including open-drain current limit, enable/disable control, and overvoltage shutdown. The MAX5963UTL+T can provide up to 30A of current at 5-60V, making it ideal for high voltage applications.

The MAX5963UTL+T is also commonly used in high-power applications like servers, where it is essential to ensure the safe and reliable operation of the board. With the built-in overvoltage protection, the MAX5963UTL+T can provide a robust level of safety from unexpected power surges, ensuring that the board continues to safely regulate supply voltage.

The MAX5963UTL+T can also be used in multi-piece and distributed power systems that utilize multiple power supplies. By combining the MAX5963UTL+T with various power supply modules, designers can easily create a redundant power supply architecture for mission-critical applications.

MAX5963UTL+T Working Principle

The MAX5963UTL+T hot swap controller works by providing a “magnetic-startup” style current limit. When the MAX5963UTL+T is powered up, the current limit is set to a pre-programmed level. When there is an overcurrent condition, the device will shut down and switch off the supply.

The MAX5963UTL+T also features an open-drain current limit that can be programmed to limit the output current to a safe limit. This ensures that the output current remains within an acceptable range and protects the circuit from damage due to an overcurrent condition.

The MAX5963UTL+T also includes an undervoltage lockout (UVLO) feature that shuts off the output when the input voltage drops below the set thresholds. This feature can be used to prevent the power supply from coming on until the input voltage has settled in to a safe voltage level.

The MAX5963UTL+T also includes an overvoltage protection (OVP) feature which will cut off the power supply when the output voltage rises above a predetermined level. This feature can be used to prevent the device from suffering any damage due to overvoltage conditions.

The MAX5963UTL+T also features an enable/disable signal that can be used to control the power-on/off cycle of the device. This signal allows for the user to program a safe power cycle for the device to reduce the risk of malfunctions and protect the device from unexpected power-on or power-down conditions.

Conclusion

The MAX5963UTL+T hot swap controller is an ideal solution for a wide range of applications requiring high power current regulation and shutdown control. Its advanced features and wide operating range make it a suitable choice for many high power applications. The MAX5963UTL+T ensures a safe and reliable hot swap solution with its advanced current limit, enable/disable signal, overvoltage protection, and undervoltage lockout features.
