The LTC4252CCMS-2#PBF is a high-performance negative voltage hot swap controller designed by Linear Technology, which is now part of Analog Devices. This sophisticated integrated circuit allows for the safe insertion and removal of boards in live backplane systems by controlling the power supply to the board.

Key Features

• Hot Swap Control: The LTC4252CCMS-2#PBF enables electronic circuit boards to be hot-swapped without turning off the system power. This feature is crucial for systems that require uninterrupted operation and maintenance.
• Voltage Range: It operates with a negative voltage range, which is ideal for systems that utilize negative supply voltages, enhancing its versatility in various applications.
• Adjustable Current Limit: The device includes an adjustable overcurrent function. This allows the user to set a precise current limit threshold to protect the system from excessive current draw during insertion.
• Gate Drive for External N-Channel MOSFET: The controller provides a gate drive for an external N-Channel MOSFET, ensuring efficient power management and distribution.
• Multi-Function Timer: An onboard multi-function timer offers programmable overcurrent auto-retry functionality, ensuring that the system attempts to power on the board again after a fault condition.

Applications

The LTC4252CCMS-2#PBF is particularly useful in systems that cannot tolerate power-down sequences and require continuous operation, such as:

• Telecommunications equipment
• Network servers and routers
• Industrial systems
• Data storage systems
