Wide Input Supply Range: −36 V to −80 V  
Transient Rating to −100 V  
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 magnitude limiting, easily  
programmed by sense resistor value and a single-  
external capacitor.
