FEATURES  
DESCRIPTIO  
The LTC®1733 is a standalone constant-current/  
constant-voltage linear charger for lithium-ion batteries  
withanon-chippowerMOSFET.Internalthermalfeedback  
regulates the charge current to limit die temperature  
during high power operation or high ambient temperature  
conditions. This feature allows the user to program a high  
charge current without risk of damaging the LTC1733 or  
the handheld product.

Thermal Regulation Maximizes Charging Rate  
without Risk of Overheating*  
No External MOSFET, Sense Resistor or Blocking  
Diode Required  
Up to 1.5A Charge Current  
Preset Charge Voltage with 1% Accuracy  
Programmable Charge Current with 7% Accuracy

No external current sense resistor is needed and no  
blocking diode is required due to the internal MOSFET  
architecture. The charge current and charge time can be  
set externally with a single resistor and capacitor, respec-  
tively. When the input supply (wall adapter) is removed,  
the LTC1733 automatically enters a low current sleep  
mode, dropping the battery drain current to less than 5µA.  
Thermistor Input for Temperature Qualified Charging  
AC Present Logic Output  
4.1V/4.2V Pin Selectable Output Voltage  
The LTC1733 also includes NTC temperature sensing,  
C/10 detection circuitry, AC present logic, 4.1V/4.2V pin  
selectability and low battery charge conditioning (trickle  
charging).
