device and reverse blocking, it offers a constant  
current / constant voltage charge algorithm with a  
user-programmable charge current level. The two  
step-down converters have been designed to mini-  
mize external component size and maximize effi-  
ciency over the entire load range. Each converter  
has independent enable and input voltage pins and  
can provide 600mA of load current.  
Functional Description  
The AAT2550 is a highly integrated power manage-  
ment IC comprised of a battery charger and two  
step-down voltage converters. The battery charger  
is designed for charging single-cell lithium-ion /  
polymer batteries. Featuring an integrated pass
