LTC4216CMS - Hot Swap Controller from Linear Technology

The LTC4216CMS is a sophisticated Hot Swap controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This compact and feature-rich component is housed in a MSOP-10 package and is engineered to manage the inrush current during system power-up or card insertion, preventing glitches on the power supply rail and protecting both the card and the backplane from the deleterious effects of large current spikes.

Key Features

• Adjustable Supply Voltage: The LTC4216CMS can operate over a wide supply voltage range from 2.9V to 26.5V, making it highly versatile for various applications.
• Overcurrent Protection: It includes a circuit breaker function with an adjustable response time, providing reliable protection against overcurrent conditions.
• High-Speed Operation: With a fast response time to fault conditions, the LTC4216CMS can quickly disconnect the load before any damage occurs.
• Adjustable Inrush Current Control: The soft-start capability allows for adjustable inrush current limiting, which is essential for managing power-up sequences and reducing stress on the power source and load capacitors.
• Power Good Output: A 'power good' output signal is provided, which can be used to enable downstream converters and loads once the supply has been properly established and is within regulation.
• Undervoltage and Overvoltage Lockout: The LTC4216CMS includes undervoltage and overvoltage lockout features that prevent operation under abnormal voltage conditions, ensuring the protection of sensitive electronic components.

Applications

The LTC4216CMS is ideal for a range of applications requiring reliable power management and protection, including:

• Network Servers and Storage Systems
• Telecommunications Equipment
• Industrial Systems
• High Availability Systems
• Hot Swap Power Supplies

This Hot Swap controller is an essential component for systems that demand high reliability, robust protection, and seamless operation under a variety of conditions. By integrating the LTC4216CMS into your design, you ensure that your systems maintain integrity and performance even in the most demanding hot-swap scenarios.
