LTC1647-2CS8#PBF - Dual Hot Swap Controller from Linear Technology

The LTC1647-2CS8#PBF is a sophisticated, dual-channel Hot Swap controller designed by Linear Technology, now part of Analog Devices, to manage the safe insertion and removal of circuit boards from live backplanes. This high-performance product is encapsulated in an 8-lead narrow SO package, making it suitable for space-constrained applications.

Key Features

• Electronic Circuit Breaker: The LTC1647-2CS8#PBF features an electronic circuit breaker function that provides overcurrent protection by sensing the voltage drop across a sense resistor and responding to an overcurrent condition.
• Adjustable Overcurrent and Overvoltage Protection: Users can set thresholds for overcurrent and overvoltage protection to ensure precise control over the power supply parameters, enhancing the safety and reliability of the system.
• Independent Controls: Each channel can be independently controlled, allowing for greater flexibility in managing the power-up and power-down sequences of two separate loads.
• Glitch Filtering: The controller includes glitch filtering to prevent nuisance tripping due to transient conditions, ensuring stable operation under various electrical disturbances.
• Gate Voltage Clamping: Integrated gate voltage clamping protects the external N-channel MOSFETs used to control the power to the load, further safeguarding the system from potential damage.
• Power Good Output: This feature offers a real-time status indication of the output voltage, enabling system monitoring and diagnostics.
• Under Voltage Lockout (UVLO): The UVLO function ensures that the controller operates only when the input voltage is within the specified range, preventing malfunction due to low input supply.

Applications

The LTC1647-2CS8#PBF is ideal for a wide array of applications that require reliable power management and protection, such as:

• Redundant Power Systems
• Network Servers and Storage Systems
• Telecommunications Equipment
• Industrial Systems

With its robust feature set and compact form factor, the LTC1647-2CS8#PBF is a versatile solution for managing power in critical systems where uptime and reliability are paramount.
