Datasheet Summary
General Description
The AAT3682 is a lithium-ion/polymer linear battery charger. It is designed for pact portable applications with a single-cell battery. The AAT3682 precisely regulates battery charge voltage and charge current, and offers an integrated pass device, minimizing the number of external ponents required.
The AAT3682 charges the battery in three different phases: preconditioning, constant current, and constant voltage. In preconditioning mode, the charge current has two different levels and is controlled by one external pin. Battery charge temperature and charge state are carefully monitored for fault conditions. A battery charge stable monitor output pin is provided to...
