LTC1642IGN#TRPBF - Hot Swap Controller from Analog Devices Inc.

The LTC1642IGN#TRPBF is a sophisticated Hot Swap controller IC designed by Analog Devices Inc., an industry leader in high-performance analog technology. This integrated circuit is engineered to allow safe insertion and removal of electronic boards from a live backplane or other powered systems. The LTC1642IGN#TRPBF is housed in a 16-pin SSOP package, offering a compact solution for managing the inrush current during the hot-swapping process, thus preventing glitches on the power supply rail and protecting both the electronic board and the backplane from damage.

Key Features:

• Electronic Circuit Breaker: The device features an adjustable electronic circuit breaker function, which provides overcurrent protection by monitoring the voltage across a sense resistor to detect excessive load currents.
• Adjustable Inrush Current Control: Users can set the inrush current limit via an external capacitor, which allows for a controlled ramp-up of the supply voltage to the load, reducing stress on the system components.
• Undervoltage Lockout (UVLO): The LTC1642IGN#TRPBF includes an undervoltage lockout feature that ensures the controller remains off until the input supply voltage reaches a safe operating level.
• Overvoltage Protection: This Hot Swap controller also provides overvoltage protection, preventing damage to the load in the event of a supply voltage surge.
• Power Good Output: A 'power good' output indicator is available, which signals when the output voltage is within nominal operating levels, offering a reliable status feedback for system monitoring.
• Gate Drive for External N-Channel MOSFET: The device is capable of driving an external N-Channel MOSFET, offering flexibility in choosing the appropriate MOSFET for the application based on the current and thermal requirements.

Applications:

The LTC1642IGN#TRPBF is ideal for a variety of applications that require hot swapping capabilities, such as:

• Redundant Power Supplies
• RAID Systems
• Server and Telecom Systems
• Network Routers and Switches

With its robust set of features and protections, the LTC1642IGN#TRPBF from Analog Devices Inc. is a reliable and efficient solution for managing power distribution in hot-swappable systems, ensuring system stability and protecting against electrical faults.
