FEATURES  
DESCRIPTIO  
■
Programmable Charge Current Up to 800mA  
The LTC®4054 is a complete constant-current/constant-  
voltage linear charger for single cell lithium-ion batteries.  
Its ThinSOT package and low external component count  
make the LTC4054 ideally suited for portable applications.  
Furthermore, theLTC4054isspecificallydesignedtowork  
within USB power specifications.  
■
No MOSFET, Sense Resistor or Blocking  
Diode Required  
Complete Linear Charger in ThinSOTTM Package for  
Single Cell Lithium-Ion Batteries  
Constant-Current/Constant-Voltage Operation with  
Thermal Regulation* to Maximize Charge Rate  
Without Risk of Overheating  
Charges Single Cell Li-Ion Batteries Directly  
from USB Port  
■
■
■
No external sense resistor is needed, and no blocking  
diode is required due to the internal MOSFET architecture.  
Thermal feedback regulates the charge current to limit the  
die temperature during high power operation or high  
ambient temperature. The charge voltage is fixed at 4.2V,  
andthechargecurrentcanbeprogrammedexternallywith  
a single resistor. The LTC4054 automatically terminates  
the charge cycle when the charge current drops to 1/10th  
the programmed value after the final float voltage is  
reached.

25µA Supply Current in Shutdown  
2.9V Trickle Charge Threshold (LTC4054)  
Available Without Trickle Charge (LTC4054X)  
Soft-Start Limits Inrush Current  
Available in 5-Lead SOT-23 Package  
U
When the input supply (wall adapter or USB supply) is  
removed, the LTC4054 automatically enters a low current  
state, dropping the battery drain current to less than 2µA.  
The LTC4054 can be put into shutdown mode, reducing  
the supply current to 25µA.  
Otherfeaturesincludechargecurrentmonitor,undervoltage  
lockout, automatic recharge and a status pin to indicate  
charge termination and the presence of an input voltage.
