LM3420-4.2, -8.2, -8.4, -12.6, -16.8  
Lithium-Ion Battery Charge Controller  
The LM3420 is available in a sub-miniature 5-lead SOT23-5  
surface mount package thus allowing very compact designs.  
General Description  
The LM3420 series of controllers are monolithic integrated  
circuits designed for charging and end-of-charge control for  
Lithium-Ion rechargeable batteries. The LM3420 is available  
in five fixed voltage versions for one through four cell charger  
applications (4.2V, 8.2V/8.4V, 12.6V and 16.8V respec-  
tively).  
Features  
n Voltage options for charging 1, 2, 3 or 4 cells  
n Tiny SOT23-5 package  
n Precision (0.5%) end-of-charge control  
n Drive capability for external power stage  
n Low quiescent current, 85 µA (typ.)  
Included in a very small package is an (internally compen-  
sated) op amp, a bandgap reference, an NPN output transis-  
tor, and voltage setting resistors. The amplifier’s inverting in-  
put is externally accessible for loop frequency  
compensation. The output is an open-emitter NPN transistor  
capable of driving up to 15 mA of output current into external  
circuitry.  
Applications  
n Lithium-Ion battery charging  
n Suitable for linear and switching regulator charger  
designs  
A trimmed precision bandgap reference utilizes temperature  
drift curvature correction for excellent voltage stability over  
the operating temperature range. Available with an initial tol-  
erance of 0.5% for the A grade version, and 1% for the stan-  
dard version, the LM3420 allows for precision end-of-charge  
control for Lithium-Ion rechargeable batteries.
