Overview
LM3620 Lithium-Ion Battery Charger Controller June 1999 LM3620 Lithium-Ion Battery Charger Controller 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 applications.
Each version provides the option of selecting the appropriate termination voltage for either coke or graphite anode lithium cells.
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 conne...
