LTC4061-4.4  
Standalone Linear Li-Ion Battery  
Charger with Thermistor Input  
U
DESCRIPTIO  
FEATURES  
The LTC®4061-4.4 is a full-featured, flexible, standalone  
linearchargerforsingle-cell4.375VLithium-Ionbatteries.It  
is capable of operating within USB power specifications.  
■
Charge Current Programmable Up to 1A  
■
Charges Single-Cell Li-Ion Batteries Directly from  
USB Port  
■
Preset 4.375V Float Voltage with ±0.4% Accuracy  
Both programmable time and programmable current  
based termination schemes are available. Furthermore,  
the CHRG open-drain status pin can be programmed to  
indicate the battery charge state according to the needs  
of the application. Additional safety features designed to  
maximize battery lifetime and reliability include NTC bat-  
tery temperature sensing and the SmartStart charging  
algorithm.

■
No external sense resistor or external blocking diode is  
required for charging due to the internal MOSFET archi-  
tecture. Internal thermal feedback regulates the charge  
currenttomaintainaconstantdietemperatureduringhigh  
power operation or high ambient temperature conditions.  
The charge current is programmed with an external resis-  
tor. With power applied, the LTC4061-4.4 can be put into  
shutdown mode to reduce the supply current to 20µA and  
the battery drain current to less than 5µA.  
Smart Pulsing Error Feature
