The TPS2359RHH is a state-of-the-art dual-slot hot-swap power controller designed by Texas Instruments to provide a secure and efficient solution for managing power distribution in systems that require hot-swapping capabilities. This advanced integrated circuit (IC) is specifically engineered for use in systems where electronic cards or modules must be inserted or removed without disrupting the operation of the remaining system, such as servers, data storage arrays, and telecommunications equipment.

Key Features

• Integrated Dual-Slot Support: The TPS2359RHH is capable of independently controlling the power for two slots, making it an ideal choice for compact systems with multiple removable components.
• Programmable Current Limit: Users can set precise current limits for each slot to ensure protection against overcurrent conditions, which helps to prevent damage to the system and maintain operational stability.
• Fast Overcurrent Response: The device features a rapid response to overcurrent events, quickly disabling the output to protect the electronic components and the power source.
• Under-Voltage Lockout (UVLO): The TPS2359RHH includes UVLO protection, which ensures that the system operates within safe voltage levels, protecting against undervoltage conditions that could potentially harm the system's components.
• Power Good (PG) Outputs: Each slot has a dedicated PG output that provides a status signal once the output voltage is stable and within the regulated range, ensuring that the system is ready for operation.
• Thermal Shutdown: The IC also includes a thermal shutdown feature, which turns off the power controller if the temperature exceeds a safe threshold, thereby protecting the system from overheating.

Applications

The TPS2359RHH is versatile and can be used in a variety of applications that require reliable hot-swap functionality. It is particularly suitable for:

• Server and Network Racks
• RAID Systems
• Telecommunications Equipment
• Industrial Control Systems
