Product Overview: LTC4252CCMS-1#PBF

The LTC4252CCMS-1#PBF is a high-performance Negative Voltage Hot Swap Controller designed by Linear Technology, which is now part of Analog Devices. This advanced controller allows for the safe insertion and removal of electronic cards from a live backplane without causing any disruption to the existing system. It is particularly suitable for systems where negative supply voltages are used, such as telecommunications and data networking equipment.

Key Features

• Integrated Charge Pump: The device includes an on-chip charge pump that provides the gate drive for an external N-channel MOSFET, eliminating the need for additional external components.
• Adjustable Current Limit: Users can set the current limit threshold through an external resistor, providing flexibility for various applications and protecting the system from overcurrent conditions.
• Fast Response to Faults: The LTC4252CCMS-1#PBF offers quick response to overcurrent and short-circuit events, enhancing the reliability and robustness of the system.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature ensures that the controller remains off unless the supply voltage is within an acceptable range.
• Power Good Output: This output signal indicates when the output voltage is within a specified range, providing a status check for system monitoring.
• Thermal Shutdown: To protect against overheating, the controller includes a thermal shutdown mechanism that turns off the MOSFET if the temperature exceeds a certain limit.

Applications

• Telecom and Datacom Systems
• Network Servers and Routers
• Industrial Systems
• High Availability Systems
