BatteryManager
General Description
The AAT3686 BatteryManager is a highly integrated
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 AAT3686 precisely regulates battery charge
voltage and current for 4.2V lithium-ion/polymer
battery cells. Adapter charge current rates can be
programmed up to 1.5A. In the absence of an
adapter and with a USB port connected, the battery
can also be charged by USB power. Depending on
the USB port type, the AAT3686 charge current can
be programmed for two separate levels up to
500mA. An optional Charge Reduction Loop is also
built in to allow users to charge the battery with
available current from a USB port, while keeping
the port voltage regulated. USB charging is dis-
abled when an adapter is present.
Battery temperature and charge state are fully moni-
tored for fault conditions. In the event of an over-volt-
age or over-temperature failure, the device will auto-
matically shut down, thus protecting the charging
device, control system, and the battery under charge.
Status monitor output pins are provided to indicate
the battery charge status by directly driving two exter-
nal LEDs. A serial interface output is available to
report 22 various status states to a microcontroller.
The AAT3686 is available in a Pb-free, thermally-
enhanced, space-saving TDFN34-16 (3x4mm) or
TDFN44-16 (4x4mm) package and is rated over the
-40°C to +85°C temperature range.
