LTC1643LCGN#TR - Hot Swap Controller from Linear Technology

The LTC1643LCGN#TR is a sophisticated hot swap controller designed by Linear Technology, now part of Analog Devices, to enable safe board insertion and removal from a live backplane. This integrated circuit is specifically engineered to control the power supply to plug-in boards, thereby preventing damage to connectors and circuitry that can be caused by inrush currents and voltage transients.

Key Features

• Electronic Circuit Breaker: The LTC1643LCGN#TR provides precise control over the inrush current, allowing for a smooth power-up sequence for the connected load. Its electronic circuit breaker functionality ensures that only the safe amount of current is supplied, protecting both the power source and the load from potential damage.
• Adjustable Overcurrent Protection: Users can set the overcurrent threshold according to their specific requirements, which ensures flexibility across different applications and protection tailored to the load's needs.
• Under Voltage Lockout (UVLO): The device features an under voltage lockout that prevents the power from being applied to the load if the supply voltage is too low, which could otherwise lead to unpredictable system behavior.
• Multi-Voltage Operation: This controller is capable of operating over a wide range of voltages, making it suitable for various systems and ensuring compatibility with different backplane voltages.
• Compact Packaging: The LTC1643LCGN#TR comes in a 16-pin SSOP package, which is ideal for space-constrained applications. The compact form factor allows for a more efficient use of board space.

Applications

The hot swap controller is a versatile component suitable for a wide array of applications, including:

• Data Servers and Storage Systems
• Telecommunication and Networking Equipment
• Industrial Systems
• High-Availability Systems
