The LTC4251-1CS6#TRMPBF is a negative voltage Hot Swap controller manufactured by LTC, designed to allow safe insertion and removal of boards from a live backplane, particularly in -48V systems. This device features a programmable analog current limit with a circuit breaker timer, active current limiting, and a fast feedforward path to manage peak fault currents.
Key protection mechanisms include programmable undervoltage and overvoltage detectors that disconnect the load when the input supply deviates from the desired operating range. The supply input is shunt regulated, enabling operation with very high supply voltages. A multifunction timer controls initial start-up delays and the circuit breaker's response time.
This controller is housed in a low-profile, 1mm ThinSOT™ package (SOT-23), suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C and requires a supply current of 0.8 mA typical. The circuit breaker accuracy is 20% with a threshold of 50mV.
