LTC4252A-2CMS#PBF Description

Short technical summary and product information.

The LTC4252A-2CMS#PBF by LT is a negative voltage Hot Swap controller that enables safe insertion and removal of boards from a live -48V backplane. This device features a floating topology for very high voltage operation and includes a current limit with a circuit breaker timer.

 

Key electrical characteristics include adjustable undervoltage and overvoltage protection, ensuring the load disconnects when the input supply exceeds the desired operating range. The LTC4252A-2 variant offers automatic retry after a fault condition. The controller is available in 8-Pin and 10-Pin MSOP packages, suitable for surface mount applications.

 

This Hot Swap controller is designed to manage power effectively during board insertion and removal, preventing damage to components. Its adjustable protection features allow for customization to specific system requirements, making it a versatile component for power management in systems operating with negative voltage rails.
