9-V to 80-V Operation  
High-Side Drive for External N-FET  
Programmable FET Power Limit  
Programmable Load Current Limit  
Programmable Fault Timer  
The TPS2492 and TPS2493 are easy-to-use, positive  
high voltage, 14-pin Hotswap Controllers that safely  
drive an external N-channel FET to control load  
current. The programmable power foldback protection  
ensures that the external FET operates inside its safe  
operating area (SOA) during overload conditions by  
controlling of power dissipation. The programmable  
current limit and fault timer ensure the supply,  
external FET, and load are not harmed by  
overcurrent. Features include inrush current limiting,  
controlled load turn-on, interfacing to down-stream  
DC-to-DC converters, and power feed protection.  
Load Current Monitor Output  
Power Good and Fault Outputs  
Enable/UV, OV Inputs  
Latch or Auto Restart After Fault  
EVM Available SLUU425  
Calculation Tool Available SLVC033  
The analog current monitor output provides a signal  
ready for sampling with an external A/D converter.  
APPLICATIONS  
Additional features include programmable overvoltage  
and undervoltage shutdown, power-good for  
coordinating loads with inrush, and a fault indicator to  
indicate an over-current shutdown.
