5A Integrated Hot Swap  
Controller  
FeaTures  
DescripTion  
The LTC®4232 is an integrated solution for Hot Swap  
applications that allows a board to be safely inserted and  
removed from a live backplane. The part integrates a Hot  
Swap controller, power MOSFET and current sense resis-  
tor in a single package for small form factor applications.

Power Good and Fault Outputs  
The LTC4232 provides separate inrush current control  
and a 10% accurate 5A current limit with foldback cur-  
rent limiting. The current limit threshold can be adjusted  
dynamically using an external pin. Additional features  
include a current monitor output that amplifies the sense  
resistor voltage for ground referenced current sensing  
andaMOSFETtemperaturemonitoroutput.Thermallimit,  
overvoltage, undervoltage and power good monitoring  
are also provided. For a 2A pin compatible version, see
