LTC4251CS6 Description

Short technical summary and product information.

The LTC4251CS6 is a negative voltage Hot Swap controller from Linear Technology (LT) designed to allow safe insertion and removal of boards from a live backplane, particularly in -48V systems.

 

This controller features a programmable analog current limit with a circuit breaker timer, providing three stages of current limiting to manage fault conditions. It also includes programmable undervoltage and overvoltage detectors to protect the load. The device operates with a floating topology, enabling very high voltage operation.

 

Packaged in a compact SOT-23 (ThinSOT) package, the LTC4251CS6 is suitable for space-constrained applications. Its features make it ideal for electronic circuit breakers and hot board insertion scenarios in telecom systems and other applications requiring robust power management and protection.

 

Key specifications include a programmable analog current limit, a circuit breaker with a 50mV threshold and 20% accuracy, and programmable undervoltage/overvoltage protection. The operating temperature range is 0 to 70°C, and it supports input voltages from -15V to -500V.
