BatteryManager

General Description

Features

The AAT3687 BatteryManager is a highly integrat-

ed single-cell lithium-ion/polymer battery charger

IC designed to operate with AC adapter inputs. It

requires a minimum number of external compo-

nents. The AAT3687 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. An active

thermal management system regulates the fast

charge constant current for all ambient tempera-

ture and input vs. output voltage conditions.

Serial Interface Status Report

12-Pin 3x3mm TDFN Package

-40°C to +85°C Temperature Range

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. A serial interface

output is available to report 12 various charging

status states to a microcontroller.

•

Applications

The AAT3687 is available in a Pb-free, thermally-

enhanced, space-saving 12-pin TDFN 3x3mm

package and is rated over the -40°C to +85°C tem-

perature range.
