BatteryManager
General Description
The AAT3688 BatteryManager is a highly inte-
grated single cell lithium-ion/polymer battery
charger IC designed to operate with USB port
inputs. It requires the minimum number of external
components.
The AAT3688 precisely regulates battery charge
voltage and current for 4.2V lithium-ion/polymer
battery cells. Depending on the USB port type, the
AAT3688 charge current can be programmed for
two separate levels up to 500mA. An optional
Charge Reduction Loop is built in to allow users to
charge the battery with available current from a
USB port, 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 AAT3688 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.
