LM3622 Datasheet Lithium-ion Battery Charger Controller

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3622 Lithium-Ion Battery Charger Controller February 2000 LM3622 Lithium-Ion Battery Charger.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM3622 is a charge controller for Lithium-Ion batteries.

This monolithic integrated circuit accurately controls an external pass transistor for precision Lithium-Ion battery charging.

The LM3622 provides a constant voltage or constant current (CVCC) configuration that changes, as necessary, to optimally charge lithium-ion battery cells.
