LTC1471CS#TRPBF - Low Power Single Hot Swap Controller

The LTC1471CS#TRPBF from Linear Technology is a high-performance, single-channel Hot Swap controller designed to allow the safe insertion and removal of boards in live backplane systems. This device is particularly suited for applications that require a compact and efficient solution for controlling the power supply to plug-in boards, without causing any disruption to the main system's power bus.

Key Features

• Wide Operating Voltage Range: The LTC1471CS#TRPBF operates over a wide voltage range from 2.7V to 12V, making it versatile for various applications.
• Adjustable Current Limit: Users can set the current limit threshold with an external resistor, allowing for precise control over the power delivered to the load.
• Low Quiescent Current: With a low quiescent current of just 175µA, this controller helps to minimize power consumption when the load is not active, making it ideal for power-sensitive applications.
• Fast Response Time: The device features a quick response to fault conditions, ensuring protection against overcurrent and short-circuit events.
• Automatic Retry or Latch Off: After a fault condition occurs, the LTC1471CS#TRPBF can be configured to either attempt a power-on retry or to latch off, providing flexibility in handling fault conditions.
• Thermal Shutdown: An integrated thermal shutdown feature protects the device and the system from damage due to excessive heat.
• Under Voltage Lockout (UVLO): The UVLO function ensures that the controller remains off if the supply voltage is too low, preventing erratic operation.

Applications

The LTC1471CS#TRPBF is ideal for a range of applications, including:

• Network servers and storage systems
• Telecommunications equipment
• Industrial systems
• Modular power supplies
• Redundant power systems

With its robust feature set and Linear Technology's reputation for high-quality power management solutions, the LTC1471CS#TRPBF is a reliable choice for system designers looking to implement Hot Swap capabilities with minimal impact on the power budget and system real estate.
