LTC4078/LTC4078X  
Dual Input Li-Ion Battery  
Charger with Overvoltage Protection  
FEATURES  
DESCRIPTION  
The LTC®4078/LTC4078X are standalone linear chargers  
that are capable of charging a single-cell Li-Ion/Polymer  
batteryfrombothwalladapterandUSBinputs.Thechargers  
can detect power at the inputs and automatically select  
the appropriate power source for charging.

No external sense resistor or blocking diode is required  
for charging due to the internal MOSFET architecture. The  
LTC4078/LTC4078Xfeatureamaximum22Vratingforboth  
wall adapter and USB inputs, although charging stops if  
the selected power source exceeds the overvoltage limit.  
Internal thermal feedback regulates the battery charge  
current to maintain a constant die temperature during  
high power operation or high ambient temperature con-  
ditions. The float voltage is fixed at 4.2V and the charge  
current is programmed with an external resistor. The  
LTC4078/LTC4078X terminate the charge cycle when the  
charge current drops below the programmed termination  
threshold after the final float voltage is reached.
