Introduction
The LM5068MM-2 is an integrated hot swap controller from Texas Instruments, specifically designed for managing the insertion, removal, and power distribution of hot swapped board-mounted components. This device is part of a family of 10 pin low-voltage smart power switch ICs, and is the second in the family for providing hot swap functionality. The LM5068MM-2 is also configurable for different conditions and protection, and performs monitoring of current, voltage and temperature for direct connection to PPTC-type resettable fuses.Features
The LM5068MM-2 provides several features to ensure that the board mounted components are protected while in hot swap mode. These features include, but are not limited to, over-voltage protection and current steering control.The over-voltage protection is set by the internal OVP circuit, which monitors the output voltage of the system and shuts off the power if the voltage exceeds a predetermined threshold. This provides the system with an added layer of safety, reducing the chance of damage or destruction due to voltage fluctuations.The current steering control allows the LM5068MM-2 to take control of the input and output power lines, monitoring the current and working to ensure that the board mounted components remain below their maximum current threshold.Application Fields
The LM5068MM-2 is widely used in fields that require hot swapped components to be monitored and managed. These fields include, but are not limited to:* Automotive: The LM5068MM-2 is used to manage the removal and insertion of components in the automotive industry, providing the necessary protection to ensure that components do not get damaged while in hot swap mode. * Office Products and Computers: The LM5068MM-2 is used in the hard drive and main board hot swap systems of computer and office products to ensure that the components remain within the proper conditions and do not get damaged.* Aerospace: The LM5068MM-2 is also used to manage hot swapped components in the aerospace industry, and provide the necessary safety measures for components in hostile environments.Working Principle
The LM5068MM-2 works by monitoring and controlling the input and output power lines of board mounted components in order to ensure that they remain within the proper temperature and current thresholds.The device works in the following steps: 1. The LM5068MM-2 prompts the output to put an input current limit to a certain level.2. The LM5068MM-2 monitors the output voltage while the device is in hot swap mode.3. If the output voltage exceeds the internal OVP circuit threshold, the power is shut off, protecting the board mounted components from damage.4. The LM5068MM-2 then monitors the temperature and current of the board mounted components in order to ensure that the components remain within their respective current and temperature thresholds. 5. Once the output voltage reaches the proper level, the LM5068MM-2 will restore power, allowing the board mounted components to continue to function normally.Conclusion
The LM5068MM-2 is an integrated hot swap controller from Texas Instruments, specifically designed for monitoring and controlling the hot swapped board mounted components. The device provides comprehensive over-voltage protection and current steering control, ensuring that the components remain within the proper temperature and current thresholds. The LM5068MM-2 is widely used in a variety of industries, including automotive, office products and computers, and aerospace. It works by monitoring both the input and output current and voltage, and shutting off the power if the voltage exceeds a predetermined threshold, providing the system with an added layer of safety.The specific data is subject to PDF, and the above content is for reference
