LTC1643AHCGN - Hot Swap Controller from Linear Technology

The LTC1643AHCGN is a sophisticated Hot Swap controller integrated circuit designed by Linear Technology, now part of Analog Devices, to manage the safe insertion and removal of circuit boards from live backplanes. This component is housed in a 16-lead SSOP package and is specifically engineered to ensure that electronic systems remain stable and protected during the hot-swapping process.

Key Features

• Advanced Electronic Circuit Breaker: The LTC1643AHCGN is equipped with an electronic circuit breaker function that provides precise overcurrent protection. This feature helps to prevent damage to the power supply and other components in the event of a fault condition.
• Adjustable Overcurrent and Overvoltage Protection: Users can set the overcurrent threshold and overvoltage protection levels according to their system requirements, ensuring tailored protection for sensitive circuitry.
• High Voltage Operation: The device is capable of operating with supply voltages up to 16.5V, making it suitable for a broad range of applications, including those that require a 12V nominal supply.
• Gate Voltage Clamping: To protect external N-channel MOSFETs, the LTC1643AHCGN includes gate voltage clamping, ensuring that the gate-source voltage does not exceed safe levels during operation.
• Automatic Retry or Latch Off: After a fault condition is detected, the device can be configured for either automatic retry or latch-off, providing flexibility in response to system errors.
• Undervoltage Lockout: The undervoltage lockout (UVLO) feature ensures that the controller remains off until the supply voltage reaches a safe operating level, preventing malfunction at low voltages.

Applications

The LTC1643AHCGN is ideal for a variety of applications that require reliable power management and protection, such as:

• Redundant Power Systems
• Industrial Control Systems
• Network Servers and Storage Systems
• Telecommunications Equipment

With its robust feature set and high-reliability design, the LTC1643AHCGN Hot Swap controller is an essential component for engineers looking to enhance system safety and maintain uptime in critical applications.
