Product Overview: LTC4252-2CMS8#PBF

The LTC4252-2CMS8#PBF is a high-quality Negative Voltage Hot Swap Controller designed by Linear Technology, now part of Analog Devices, to manage the insertion and removal of cards from a live backplane. This component ensures safe board insertion and extraction from a -48V backplane typically used in telecom systems, central offices, and network equipment.

Key Features

• Hot Swap Controller: Allows for the safe insertion and removal of electronic components without the need to power down the system.
• Negative Voltage Operation: Specifically tailored for systems that operate with negative supply voltages, such as -48V telecom systems.
• Adjustable Current Limit: Features an adjustable current limit to provide flexibility for various card designs and to protect against overcurrent conditions.
• Overcurrent Fault Timer: Incorporates an overcurrent fault timer that ensures the system reacts appropriately during prolonged overcurrent conditions.
• Gate Voltage Clamp: Includes a gate voltage clamp for the external N-channel MOSFET to protect against overvoltage stress.
• Undervoltage Lockout: An undervoltage lockout (UVLO) feature ensures that the system operates within safe voltage levels.
• Multi-Package Option: Available in the 8-lead MSOP package, offering a compact solution for space-constrained applications.
