Wide Input Supply Range: −20 V to −80 V  
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 converters. The TPS2392  
and TPS2393 also provide the basic hot swap functions  
of electrical isolation of faulty cards, filtered protection  
against nuisance overcurrent trips, and single-line fault  
reporting. The 44-pin part supports designs where  
telecomm creepage and clearance requirements must  
be followed.
