BatteryManager
General Description
The AAT3689 BatteryManager is a highly integrat-
ed single cell lithium-ion/polymer battery charger
IC designed to operate with USB port and AC
adapter inputs. It requires a minimum number of
external components.
The AAT3689 precisely regulates battery charge
voltage and current for 4.2V lithium-ion/polymer bat-
tery cells. Adapter charge current rates may be pro-
grammed up to 1.0A. In the absence of an adapter
and with a USB port connected, the battery can also
be charged by USB power. The USB charge current
can be programmed up to 500mA. USB charging is
disabled when an adapter is present.
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.
The AAT3689 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.
