LTC4053-4.2  
USB Compatible  
Lithium-Ion Battery Charger  
with Thermal Regulation

FEATURES  
DESCRIPTIO  
The LTC®4053 is a standalone linear charger for lithium-  
ionbatteriesthatcanbepowereddirectlyfromaUSBport.  
The IC contains an on-chip power MOSFET and eliminates  
the need for an external sense resistor and blocking diode.  
Thermal regulation automatically adjusts charge current  
tolimitdietemperatureduringhighpowerorhighambient  
temperature conditions. This feature protects the end  
product and the LTC4053 from thermal stress while the IC  
charges the battery at maximum rate without interruption.  
■
Charges Single-Cell Li-Ion Batteries Directly from  
USB Port  
■
Thermal Regulation Maximizes Charge Rate  
without Risk of Overheating*  
■
Programmable Charge Current with ±7% Accuracy  
■
Low Dropout Operation  
■
No External MOSFET, Sense Resistor or Blocking  
Diode Required  
■
Programmable Charge Termination Timer  
■
Preset Charge Voltage with ±1% Accuracy  
The charge current and charge time can be set externally  
with a single resistor and capacitor, respectively. When  
the input supply (wall adapter or USB supply) is removed,  
the LTC4053 automatically enters a low current sleep  
mode, dropping the battery drain current to less than 5µA.  
■
C/10 Charge Current Detection Output  
■
AC Present Logic Output  
■
25µA Supply Current in Shutdown Mode  
■
Automatic Recharge  
■
Charge Current Monitor Useful for Gas Gauging  
■
■
The LTC4053 also includes NTC temperature sensing,  
C/10 detection circuitry, AC present logic, low battery  
chargeconditioning(tricklecharging)andshutdown(25µA  
supply current).  
Thermistor Input for Temperature Qualified Charging  
Available in 10-pin thermally enhanced MSOP and  
low profile (0.75mm) 3mm × 3mm DFN packages
