FEATURES  
DESCRIPTIO  
The LTC®4059/LTC4059A are constant-current/constant-  
voltagelinearchargersforsinglecelllithium-ionbatteries.  
Their 2mm × 2mm DFN package and low external compo-  
nent count make these chargers especially well suited for  
portable applications. Furthermore, they are designed to  
work within USB power specifications.  
Programmable Charge Current Up to 900mA  
Charge Current Monitor Output for Charge  
Termination  
Constant-Current/Constant-Voltage Operation with  
Thermal Regulation to Maximize Charging Rate  
Without Risk of Overheating  
Constant-Current Source Mode for Charging  
Nickel Batteries (LTC4059 Only)  
ACPR Pin Indicates Presence of Input Supply  
(LTC4059A Only)  
No External MOSFET, Sense Resistor or Blocking  
Diode Required  
Operating Supply Voltage from 3.75V to 8V  
Charges Single Cell Li-Ion Batteries Directly from  
USB Port  
Preset 4.2V Charge Voltage with 0.6% Accuracy  
10µA Supply Current in Shutdown Mode  
Tiny 6-Lead (2mm × 2mm) DFN Package  
U
No external sense resistor, MOSFET or blocking diode is  
required. Thermal feedback regulates the charge current  
tolimitthedietemperatureduringhighpoweroperationor  
high ambient thermal conditions. The charge voltage is  
fixed at 4.2V and the charge current is programmable.  
When the input supply (wall adapter or USB supply) is  
removed,theLTC4059/LTC4059Aautomaticallyenteralow  
currentstate,droppingthebatterycurrentdraintolessthan  
1µA. With power applied, they can be put into shutdown  
mode, reducing the supply current to 10µA.  
The LTC4059A features an open-drain status pin to indi-  
cate the presence of an input voltage. The LTC4059 can be  
used as a constant-current source to charge Nickel cells.  
Other features include undervoltage lockout protection  
and a current monitor pin which can indicate when to  
terminate a charge cycle.
