Wide Input Supply Range: −36 V to −80 V  
Transient Rating to −100 V  
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 current faults, while the  
TPS2391 periodically retries the load in the event  
of a fault.
