LTC4160/LTC4160-1  
Switching Power Manager  
with USB On-The-Go And  
Overvoltage Protection  
FEATURES  
DESCRIPTION  
The LTC®4160/LTC4160-1 are high efficiency power man-  
agementandLi-Ion/PolymerbatterychargerICs.Theyeach  
include a bidirectional switching PowerPath™ controller  
with automatic load prioritization, a battery charger, and  
an ideal diode.  
n
Bidirectional Switching Regulator Makes Optimal  
Use of Limited Power Available from USB Port and  
also Provides a 5V Output for USB On-The-Go  
n
Overvoltage Protection Guards Against Damage  
n
180mΩ Internal Ideal Diode Plus Optional External  
Ideal Diode Controller Seamlessly Provides Low  
Loss PowerPath When Input Power is Limited or  
Unavailable  
TheLTC4160/LTC4160-1’sbidirectionalswitchingregulator  
transfers nearly all of the power available from the USB  
port to the load with minimal loss and heat which eases  
thermalconstraintsinsmallspaces.Thesedevicesfeature  
a precision input current limit for USB compatibility and  
Bat-Trackoutputcontrolforefficientcharging. Inaddition,  
the ICs can also generate 5V at 500mA for USB On-The-  
Go applications.
