Lithium-Ion/Polymer Battery Charger  
BatteryManager  
General Description  
Features  
The AAT3681 BatteryManager is a member of  
AnalogicTech's Total Power Management IC™  
(TPMIC™) product family. This product is an inte-  
grated single cell lithium-ion/polymer battery charg-  
er IC, designed to operate from a DC power source  
or USB port up to an input voltage of 6.5V. It requires  
just one external component.  
USB or AC Adapter System Power Charger  
— Programmable from 15mA to 300mA  
4.0V ~ 6.5V Input Voltage Range  
High Level of Integration with Internal:  
— Charging Device  
— Reverse Blocking Diode  
Automatic Current Sensing  
Automatic Recharge Sequencing  
Full Battery Charge Auto Turn Off/Sleep  
Mode/Charge Termination  
The AAT3681 precisely regulates battery charge  
voltage and current for 4.2V (4.375V option) lithium-  
ion/polymer battery cells. When charged from an  
AC adapter or USB port, the battery charging cur-  
rent can be set by an external resistor up to 300mA.  
Shutdown Current <1µA  
Automatic Trickle Charge for Battery Pre-  
Conditioning  
Battery charge state is continuously monitored for  
fault conditions. In the event of an over-voltage,  
short-circuit, or over-temperature failure, the  
device will automatically shut down, thus protecting  
the charging device, control system, and the bat-  
tery under charge. A status monitor output pin is  
provided to indicate the battery charge status by  
directly driving an external LED.  
Over-Voltage and Emergency Thermal  
Protection  
Power On Reset and Soft Start  
LED Status Pin  
8-Pin 2.0x2.1mm SC70JW Package  
Applications  
The AAT3681 is available in a Pb-free, thermally  
enhanced, space-saving 8-pin 2.0x2.1mm SC70JW  
package and is specified for operation over the  
-40°C to +85°C temperature range.
