General Description
The AAT3682 is a lithium-ion/polymer linear battery
charger. It is designed for compact portable applications
with a single-cell battery. The AAT3682 precisely regu-
lates battery charge voltage and charge current, and
offers an integrated pass device, minimizing the number
of external components required.
The AAT3682 charges the battery in three different
phases: preconditioning, constant current, and constant
voltage. In preconditioning mode, the charge current has
two different levels and is controlled by one external pin.
Battery charge temperature and charge state are care-
fully monitored for fault conditions. A battery charge
stable monitor output pin is provided to indicate the bat-
tery charge status through a display LED or interface to
a system controller. The AAT3682 has a sleep mode
option for when the input supply is removed. In this
mode, it draws only 2.0μA of typical current.
The AAT3682 is available in a Pb-free, 16-pin QFN44
package and is specified over the -20°C to +70°C tem-
perature range.

Function
Battery temperature sense input.
Not connected.
Battery charger status output. Connect an LED in series with 2.2kfrom STAT to VIN for a visual
monitor battery charge state or connect to a microcontroller to monitor battery status. A 100k
resistor should be placed between STAT and VIN for this function.
Common ground connection.
Battery charge control output.
Battery trickle charge control input. Connect this pin to VSS to double the battery trickle charge cur-
rent. Leave this pin oating for normal trickle current (10% of full charge current). To enter micro-
controller fast-read status, pull this pin high during power up.
Battery charge control output. Current regulated output to charge the battery. For best operation, a
0.1μF ceramic capacitor should be placed between BAT and GND.
Common ground connection.
Input voltage for biasing the pass device.
Battery charge power input.
Current sense input.
Battery voltage sense input.
AAT3682 bias input power.
Exposed paddle (bottom); connect to GND directly beneath the package.
