Replaces OR-ing Diodes  
The TPS2350 is a hot swap power manager  
optimized for replacing OR-ing diodes in  
redundant power −48-V systems. The TPS2350  
operates with supply voltages from −12 V to  
−80 V, and withstands spikes to −100 V.  
Operating Supply Range of −12 V to −80 V  
Withstands Transients to –100 V  
Programmable Current Limit  
Programmable Linear Inrush Slew Rate  
Programmable UV/OV Thresholds  
Programmable UV and OV Hysteresis  
Fault Timer to Eliminate Nuisance Trips  
Power Good and Fault Outputs  
The TPS2350 uses two power FETs as low  
voltage drop diodes to efficiently select between  
two redundant power supplies. This minimizes  
system power dissipation and also minimizes  
voltage drop through the power management  
chain.  
14-Pin SOIC and TSSOP Package  
The TPS2350 also uses a third power FET to  
provide load current slew rate control and peak  
current limiting that is programmed by one resistor  
and one capacitor. The device also provides a  
power good output to enable down-stream power  
converters and a fault output to indicate load  
problems.
