The LTC4350IGN#PBF is a robust, high-performance Hot Swap™ controller from Linear Technology, designed to regulate the inrush current and manage power distribution in systems where multiple boards or cards are hot-swappable. This advanced controller is packaged in a 16-lead SSOP, offering a compact footprint for space-constrained applications.

Key Features

• Hot Swap Control: The LTC4350 allows a board to be safely inserted and removed from a live backplane. By controlling the gate voltage of an external N-channel MOSFET, the LTC4350 smoothly ramps up the load capacitor voltage, minimizing inrush current and preventing the system voltage from sagging.
• Current Limiting: The device features adjustable overcurrent protection that safeguards both the load and the power supply from damage. This is achieved through a sense resistor which allows precise control over the trip point.
• Power Good Output: A power good output signals when the output voltage is within ±10% of the input voltage, indicating that the load is properly connected and operational.
• Circuit Breaker Function: The LTC4350 incorporates a fast-acting circuit breaker function that protects against short-circuit and overcurrent conditions, enhancing system reliability.
• High Voltage Operation: With an operating range of up to 80V, the LTC4350 is suitable for managing power in high voltage systems.
