The LTC1647-1CS8#PBF is a specialized integrated circuit designed and manufactured by Linear Technology, which is now part of Analog Devices. This particular product is a Hot Swap Controller that allows a board to be safely inserted and removed from a live backplane. It is housed in an 8-lead narrow SOIC package, offering a compact solution for managing power distribution in high-availability systems.

Key Features

• Electronic Circuit Breaker: The LTC1647-1CS8#PBF is equipped with an electronic circuit breaker function, providing overcurrent protection by limiting the output current during fault conditions.
• Adjustable Overcurrent Timeout: Users can set the timeout period for overcurrent conditions, allowing for flexibility in different application requirements.
• Under-Voltage Lockout: The device includes an under-voltage lockout feature that ensures the power supply is at an adequate level before allowing the circuit to become active, thereby protecting sensitive components.
• Gate Voltage Clamped at 15V: The integrated MOSFET gate voltage is clamped at 15V to protect the gate oxide from overvoltage stress, enhancing the longevity of the device.
• Automatic Retry or Latch Off: After a fault condition, the LTC1647-1CS8#PBF can be configured to either attempt to restart automatically (auto-retry) or latch off until the system is reset manually.

Applications

The LTC1647-1CS8#PBF is suitable for a wide range of applications, particularly in systems where hot-swapping capability is essential. This includes:

• Redundant Power Supplies
• Network Servers and Storage Systems
• High-Availability Telecommunications Equipment
