The LTC4252A-2CMS#TRPBF by LT is a negative voltage Hot Swap controller that enables safe insertion and removal of boards from a live –48V backplane. Its floating topology allows for very high voltage operation. The device features a programmable soft-start current limit, a timed circuit breaker, and an active current limiting stage, complemented by a fast feedforward path to limit peak fault current.
Adjustable undervoltage and overvoltage detectors ensure the load is disconnected when the input supply deviates from the desired operating range. This specific variant, LTC4252A-2, incorporates automatic retry after a fault condition. The controller is available in an 8-pin and 10-pin MSOP package, suitable for various board space constraints.
Key electrical features include programmable current limiting with circuit breaker timer, fast response time, and programmable timer with drain voltage accelerated response. The ±1% accuracy for undervoltage/overvoltage thresholds is a notable feature of the LTC4252A series.
The LTC4252A-2CMS#TRPBF is designed for -48V backplane operation.
The LTC4252A-2 variant provides automatic retry after a fault.
