LM3620  
Lithium-Ion Battery Charger Controller  
With a trimmed output voltage regulation of 1.2% initial  
accuracy, the LM3620 provides a simple, precise solution for  
end-of-charge control of lithium-ion rechargeable cells.  
General Description  
The LM3620 series of controllers are monolithic integrated  
circuits designed to control the charging and end-of-charge  
control for lithium-ion rechargeable batteries. The LM3620 is  
available in two versions for one or two cell charger applica-  
tions. Each version provides the option of selecting the  
appropriate termination voltage for either coke or graphite  
anode lithium cells.  
The LM3620 is packaged in a miniature 5-lead SOT-23  
surface mount package for very compact designs.  
Features  
n Voltage options for charging 1 or 2 cell stacks  
n Adjustable output voltage for coke or graphite anodes  
n Precision end-of-charge voltage control  
n Wide input voltage range (4V to 30V)  
The LM3620 can operate from a wide range of DC input  
sources (4V to 30V). With no charger supply connected, the  
controller draws a quiescent current of only 10nA to minimize  
discharging of a connected battery pack.  
<
n Low off state current ( 10nA)  
The LM3620 consists of an operational transconductance  
amplifier, a bandgap voltage reference, a NPN driver tran-  
sistor and precision voltage setting resistors. The output of  
the amplifier is made available to drive an external power  
transistor if higher drive currents are required.  
n Drive provided for external power stage  
n Tiny SOT-23 package
