The TPS2398 and TPS2399 simple -48-V hot swap controllers are integrated solutions optimized for use in nominal -48-V systems. They are used in conjunction with an external N-channel MOSFET and sense resistor to enable hot swap, the insertion and removal of plug-in cards or modules in powered systems. Both devices feature inrush current slew rate and peak magnitude limiting, which are easily programmed by the sense resistor value, and a single external capacitor. They facilitate implementation of platform control of the electrical connectionor isolation of the protected load, and provide single-line load fault reporting. An on-chip timer, also set by a single capacitor, provides filtering against nuisance breaker trips. These features are all incorporated into a tiny 8-pin MSOP package. The TPS2398 latches off in response to current faults. The TPS2399 periodically retries the load, to test for the continued existence of a fault.
