FEATURES  
DESCRIPTIO  
The LTC®1731 is a complete constant-current/constant-  
voltage linear charger controller for single cell lithium-ion  
batteries. Nickel-cadmium (NiCd) and nickel-metal-hy-  
dride (NiMH) batteries can also be charged with constant  
current using external termination. The external sense  
resistor sets the charge current with 5% accuracy. An  
internal resistor divider and precision reference set the  
final float potential with ±1% accuracy. The output float  
voltage is set internally to 4.1V (LTC1731-4.1) or 4.2V  
(LTC1731-4.2).

C/10 Charge Current Detection Output  
Programmable Charge Termination Timer  
Space Saving 8-Pin MSOP Package

is Removed (7µA Battery Drain)  
Automatic Trickle Charging of Low Voltage Cells  
Programmable for Constant-Current-Only Mode  
Whentheinputsupplyisremoved,theLTC1731automati-

drain current to typically 7µA. An internal comparator  
detects the end-of-charge (C/10) condition while a pro-  
grammable timer, using an external capacitor, sets the  
total charge time. Fully discharged cells are automatically  
trickle charged at 10% of the programmed current until  
cell voltage exceeds 2.457V.
