Product Overview: LTC4350IGN from Linear Technology

The LTC4350IGN from Linear Technology is a high-performance Hot Swap Controller designed to regulate the inrush current in high-availability systems. This sophisticated component allows a board to be safely inserted and removed from a live backplane without causing any disruption to the main power supply or other boards. The LTC4350IGN is housed in a compact SSOP package, ensuring it can be accommodated in space-constrained applications.

Key Features

• Current Limiting: The LTC4350IGN effectively limits the inrush current during hot-swapping, protecting both the connector and the system's power supply from the potentially damaging effects of a sudden surge in current.
• Voltage Range: It operates over a wide range of voltages, typically from 9V to 80V, offering versatility for various system designs and ensuring compatibility with a broad spectrum of backplanes and power systems.
• Power Good Output: This feature provides a signal once the output voltage is within the acceptable range, ensuring that the downstream load is only powered when stable voltage is present.
• Gate Control for External N-Channel MOSFET: The LTC4350IGN controls an external N-Channel MOSFET to modulate the inrush current, providing a robust and efficient method for managing the power flow during insertion.
• Adjustable Current Limit: Designers can set the current limit threshold according to specific requirements, offering flexibility in the design and protection of the system.

Applications

The LTC4350IGN is ideally suited for a wide range of applications, particularly in systems where high availability is critical. These include:

• Redundant Power Supplies
• Hot Swap Rack Systems
• Industrial Computers
• Telecom Infrastructure
• Server Backplanes

With its robust feature set and ability to manage power insertion safely, the LTC4350IGN is an essential component for systems engineers who demand reliability and precision in their power management solutions. Linear Technology's commitment to quality ensures that this Hot Swap Controller will enhance the operational integrity of any high-availability system.
