The LTC1647-1IS8#PBF is a sophisticated, feature-rich Hot Swap controller from Linear Technology, designed to allow safe board insertion and removal from a live backplane. This component is housed in an 8-pin narrow SO package, making it a compact solution for managing the power supply connection in a hot-swap environment. The product is specifically engineered to control the inrush current to prevent the glitches on the supply rail that can reset other boards in the system.

One of the key features of the LTC1647-1IS8#PBF is its ability to operate over a wide voltage range, from 2.7V to 16.5V, which makes it versatile for various applications. It includes an adjustable analog current limit to provide flexibility in setting the maximum inrush current to the load. This ensures protection for both the device and the power source.

The LTC1647-1IS8#PBF also incorporates an automatic retry feature, which ensures that the system attempts to power-up again after a fault without the need for manual intervention. This is particularly useful for systems that cannot afford downtime and need to maintain continuous operation.

Key Features:

• Wide operating voltage range: 2.7V to 16.5V
• Adjustable analog current limit
• Automatic retry after fault
• Overcurrent and overtemperature protection
• Under voltage lockout
• Compact 8-pin narrow SO package

With overcurrent and overtemperature protection, the LTC1647-1IS8#PBF ensures the safety of the components connected to the power rail by shutting down the pass transistor when a fault is detected. Additionally, the under voltage lockout (UVLO) feature guarantees that the device only operates at safe voltage levels.

In summary, the LTC1647-1IS8#PBF Hot Swap controller from Linear Technology is an essential component for creating a secure and reliable hot-swap system. Its comprehensive protection features and automatic retry capabilities make it an ideal choice for critical applications where uptime is paramount.
