Product Overview: LTC4264IDE#TRPBF by Analog Devices Inc.

The LTC4264IDE#TRPBF is a sophisticated negative voltage Hot Swap™ controller from Analog Devices Inc., designed to enable safe board insertion and removal from a live backplane. This compact, feature-rich component is ideal for managing negative supply voltages in systems where electronic modules must be hot-swapped, such as servers, data centers, and telecommunications equipment.

Key Features

• Hot Swap Control: The device allows a board to be safely inserted and removed from a live backplane by controlling the inrush current to prevent glitches on the power supply rail.
• Negative Voltage Operation: Specifically designed for negative supply voltages ranging from -9V to -80V, the LTC4264IDE#TRPBF is versatile for various applications requiring negative voltage rails.
• Integrated Fault Protection: The controller provides overcurrent protection and fault isolation, ensuring that if a fault occurs on one card, it does not affect the entire system.
• Adjustable Current Limit: Users can set the current limit threshold via an external resistor, allowing for precise control based on the needs of the specific application.
• Power Good Output: A 'power good' output signal is provided to indicate when the output voltage is within a nominal operating range, which is essential for system monitoring and control.
• Compact Package: The LTC4264IDE#TRPBF is available in a 12-lead DFN package (4mm x 3mm) with an exposed pad for enhanced thermal performance, making it suitable for space-constrained applications.
