DESCRIPTION  
FEATURES  
The TPS2345 CompactPCI Hot Swap Power  
Manager (HSPM) provides highly-integrated  
supply control of three positive (3.3-V, 5-V, and  
12-V) and one negative (–12-V) supply rails with  
a minimum number of external components. A  
linear current amplifier (LCA) in each of the four  
device channels provides closed-loop control of  
load current during insertion and extraction  
events. This allows the designer to configure the  
plug-in card’s maximum inrush slew rate and  
Enables Hot Swap in CompactPCI High
