The LTC1647-1IS8 is a specialized integrated circuit designed and manufactured by Linear Technology, a brand renowned for its high-performance analog ICs. This particular product is a Hot Swap controller that allows a board to be safely inserted and removed from a live backplane. The device is housed in a narrow SO-8 package, making it suitable for space-constrained applications.

Key Features

• Electronic Circuit Breaker: The LTC1647-1IS8 is equipped with an electronic circuit breaker function that provides precise overcurrent protection. This feature ensures that the device can protect itself and other components from damage due to excessive current flow.
• Adjustable Overcurrent Threshold: Users can set the overcurrent threshold according to their specific requirements, offering flexibility and enhanced protection tailored to the application's needs.
• Automatic Retry or Latch Off: Upon detecting an overcurrent condition, the LTC1647-1IS8 can be configured to either automatically attempt to restart or latch off, providing options for system recovery strategies.
• Under Voltage Lockout: The device includes an under voltage lockout (UVLO) feature that disables the external N-channel pass transistor when the input voltage falls below a certain threshold, preventing undervoltage operation.
• SO-8 Package: The small form factor of the SO-8 package allows for efficient use of PCB space, which is crucial for compact and dense board designs.

Applications

The LTC1647-1IS8 is ideal for a wide range of applications that require safe insertion and removal of electronic components. It is particularly useful in systems where hot-swap functionality is necessary, such as:

• RAID systems
• Server backplanes
• Network routers and switches
• Telecommunications equipment
