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 respectively).
Included in a very small package is an (internally compensated) op amp, a bandgap reference, an NPN
output transistor, and voltage setting resistors. The amplifier's inverting input 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.
A trimmed precision bandgap reference utilizes temperature drift curvature correction for excellent voltage
stability over the operating temperature range. Available with an initial tolerance of 0.5% for the A grade
version, and 1% for the standard version, the LM3420 allows for precision end-of-charge control for Lithium-
Ion rechargeable batteries.
