General Description
The AAT3690 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 the minimum number of
external components.
The AAT3690 precisely regulates battery charge
voltage and current for 4.2V lithium-ion/polymer
battery cells. Adapter charge current rates can be
programmed up to 1.0A. In the absence of an
adapter and with a USB port connected, the bat-
tery can also be charged by USB power. The USB
charge current can be programmed up to 1A. A
Charge Reduction Loop is also built in to allow
users to charge the battery with the available cur-
rent from a USB port, while keeping the port volt-
age regulated. 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 condition, 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 AAT3690 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.
