Analog Devices Inc. LTC1643HCGN Hot Swap Controller

The LTC1643HCGN, manufactured by Analog Devices Inc., is a highly efficient and advanced hot swap controller designed to enable safe board insertion and removal from a live backplane. This integrated circuit helps manage the inrush current when a card is inserted, preventing glitches on the supply rail, damage to connectors, or disruption of system operation.

Key Features

• Electronic Circuit Breaker: The LTC1643HCGN features an adjustable electronic circuit breaker function, which provides precise control over the maximum current that can be drawn by the load, protecting against overcurrent conditions.
• Adjustable Inrush Current Control: Users can adjust the inrush current limit to match specific system requirements, ensuring a smooth power-up sequence for the card and reducing stress on the power supply.
• Under Voltage Lockout (UVLO): The device includes an under voltage lockout feature that ensures the controller remains off until the input supply voltage reaches a safe operating level.
• Overvoltage Protection: The LTC1643HCGN provides overvoltage protection, which safeguards the load from voltage spikes that could potentially cause damage.
• Multi-Function Timer: An onboard multi-function timer offers flexibility for setting various time-dependent functions such as circuit breaker response time and power-up delay.
• Status Indicators: Integrated status outputs allow for signaling to external microcontrollers or other monitoring systems, providing real-time information about fault conditions and operational status.

Applications

The LTC1643HCGN is ideal for a variety of applications where power management and protection are critical, including:

• Server and Telecom Hot Swap Systems
