The LT1649CS is a sophisticated hot swap controller designed by Linear Technology to ensure safe insertion and removal of printed circuit boards from a live backplane. This integrated circuit is housed in a compact surface-mount package, offering an efficient solution for managing inrush currents and protecting against overcurrent conditions in high-availability systems.

Key Features

• Adjustable Inrush Current Control: The LT1649CS provides precise control over the inrush current at the time of board insertion, minimizing the stress on connectors, capacitors, and other circuit components.
• Overcurrent Protection: It features robust overcurrent protection that safeguards the circuit by limiting the output current during fault conditions.
• High Voltage Operation: Capable of handling voltages up to 16.5V, the LT1649CS is versatile for a range of applications, including 12V and 5V systems.
• Programmable Timer: The built-in timer allows for adjustable overcurrent auto-retry delay, providing flexibility in system design and recovery protocols.
• Power Good Output: A "power good" status output is available to signal when the output voltage is within the acceptable range, enabling downstream load activation.

Applications

The LT1649CS is ideal for use in a variety of high-reliability applications such as:

• Server Backplanes
• RAID Systems
• Telecommunications Equipment
• Industrial Systems
