AAT3689
0.5A/1.0A USB Port/Adapter
Lithium-Ion/Polymer Battery Charger
General Description
BatteryManager™
Features
The AAT3689 BatteryManager is a highly integrat-
• USB/AC Adapter System Power Charger
ed single cell lithium-ion/polymer battery charger
— USB: Programmable up to 500mA
IC designed to operate with USB port and AC
— Adapter: Programmable up to 1.0A
adapter inputs. It requires a minimum number of
• 4.0V to 5.5V Input Voltage Range
external components.
• Adapter Presence Automatically Disables
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.
USB Charging
• High Level of Integration With Internal:
— Charging Devices
— Reverse Blocking Diodes
— Current Sensing
• Automatic Recharge Sequencing
• Battery Temperature Monitoring
• Full Battery Charge Auto Turn-Off
• Over-Current Protection
Battery temperature and charge state are fully
• Over-Voltage Protection
monitored for fault conditions. In the event of an
• Emergency Thermal Protection
over-voltage or over-temperature failure, the
• Power On Reset and Soft Start
device will automatically shut down, thus protecting
• 12-Pin 3x3 TDFN Package
the charging device, control system, and the bat-
tery under charge. Status monitor output pins are
provided to indicate the battery charge status by
Applications
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.
