LTC4233  
10A Guaranteed SOA  
Hot Swap Controller  
FEATURES  
DESCRIPTION  
The LTC®4233 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.  
The MOSFET Safe Operating Area is production tested  
and guaranteed for the stresses in Hot Swap applications.
