General Description
The AAT3685 BatteryManager is a highly inte-
grated single cell lithium-ion/polymer battery charg-
er IC designed to operate with USB port or line
adapter inputs. It requires the minimum number of
external components.
The AAT3685 precisely regulates battery charge volt-
age and current for 4.2V lithium-ion/polymer battery
cells. Regardless of the type of input power source
(USB or adapter), the AAT3685 can be programmed
for two separate constant current charge levels up to
1A. An optional Charge Reduction Loop is built in to
allow users to charge the battery with available cur-
rent from the charge supply, while keeping the port
voltage regulated.
Battery temperature and charge state are fully
monitored for fault conditions. In the event of an
over-voltage or over-temperature failure, the
device will automatically shut down, thus protecting
the charging device, control system, and the bat-
tery under charge. Status monitor output pins are
provided to indicate the battery charge status by
directly driving two external LEDs. Aserial interface
output is available to report any one of 14 various
status states to a microcontroller.
The AAT3685 is available in a Pb-free, thermally-
enhanced, space-saving 12-pin 3x3mm TDFN
package and is rated over the -40°C to +85°C tem-
perature range.
