TPS2390 : The TPS2390 and TPS2391 integrated circuits are hot swap power managers optimized for use in nominal −48-V systems. They are designed for supply voltage ranges up to −80 V, and are rated to withstand spikes to −100 V. In conjunction with an external N-channel FET and sense resistor, they can be used to enable live insertion of plug-in cards and modules in powered systems. Both devices provide load current slew rate and peak magnitude limiting, easily programmed by sense resistor value and a single-external capacitor. They also provide single-line fault reporting, electrical isolation of faulty cards, and protection against nuisance overcurrent trips. The TPS2390 latches off in response to cu.

TPS2392 : The TPS2392 and TPS2393 integrated circuits are hot swap power managers optimized for use in nominal −48-V systems. They operate with supply voltage ranges from −20-V to −80-V, and are rated to withstand spikes to −100 V. In conjunction with an external N-channel FET and sense resistor, they can be used to enable live insertion of plug-in cards and modules in powered systems. Each device provides load current slew rate control and peak magnitude limiting. Undervoltage and overvoltage shutdown thresholds are easily programmed via a three-resistor divider network. In addition, two active-low, debounced inputs provide plug-in insertion detection. A power good (PG) output enables downstream conv.

TPS2398 : The TPS2398 and TPS2399 integrated circuits are hot swap power managers optimized for use in nominal −48-V systems. For redundant-supply systems, they incorporate an improved circuit breaker response that provides rapid protection from short circuits, while still enabling plug-ins to tolerate large transients that can be generated by the sudden switchover to a higher voltage supply. They are designed for supply voltage ranges up to −80 V, and are rated to withstand spikes to −100 V. In conjunction with an external N-channel FET and sense resistor, they can be used to enable live insertion of plug-in cards and modules in powered systems. Both devices provide load current slew rate and peak ma.
