General Description
The AAT3682 is a lithium-ion/polymer linear battery
charger. It is designed for compact portable appli-
cations with a single cell battery. The AAT3682 pre-
cisely regulates battery charge voltage and charge
current, and offers an integrated pass device, mini-
mizing the number of external components required.
The AAT3682 charges the battery in three different
phases: preconditioning, constant current, and con-
stant 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 condi-
tions. A battery charge stable monitor output pin is
provided to indicate the battery charge status
through a display LED or interface to a system con-
troller. The AAT3682 has the sleep mode option for
when the input supply is removed. In this mode, it
draws only 2.0μA of typical current.
The AAT3682 is available in a 16-pin QFN44 and is
specified over the -20°C to +70°C temperature
range.
