General Description
The AAT3683 BatteryManager is a highly integrated sin-
gle-cell lithium-ion / polymer (Li-Ion) battery charger
that operates from a USB port or an AC adapter input up
to an input voltage of 7.5V.
The AAT3683 precisely regulates battery charge voltage
and current for 4.2V Li-Ion battery cells. The battery
charging current can be set by an external resistor up to
1A.
Digital Thermal Loop Control maintains the maximum
possible battery charging current for the given set of
input to output power dissipation and ambient tempera-
ture conditions.
Battery charge state is continuously monitored for fault
conditions. In the event of an over-current, over-voltage,
short-circuit, or over-temperature condition, the device
will shut down automatically, thus protecting the charg-
ing device, control system, and the battery under
charge. A status monitor output pin is provided to indi-
cate the battery charge status by directly driving an
external LED. An open-drain power source detection out-
put is provided to report the power supply status.
The AAT3683 is available in the Pb-free, thermally-
enhanced, space-saving 2.2 x 2.2mm 10-pin STDFN
(AAT3683-2) and 16-pin QFN33 (AAT3683-4) packages
and is specified for operation over the -40°C to +85°C
temperature range.
