Functional Description

The AAT3681A is a high performance battery charger

designed for single cell lithium-ion/polymer batteries

with up to 500mA of charge current from an external

power source. It is a stand-alone charging solution, with

just one external component required for complete func-

tionality. The AAT3681A precisely regulates battery

charge voltage and current for 4.2V lithium-ion/polymer

battery cells. The AAT3681A-5 regulates battery charge

voltage for 4.1V Lithium-ion/polymer battery cells.

Device junction temperature and charge state are fully

monitored for fault conditions. In the event of an over-

voltage or over-temperature failure, the device will auto-

matically shut down, protecting the charging device,

control system, and the battery under charge.

Charging Operation

The adapter/USB charge input constant current level can

be programmed up to 500mA for rapid charging applica-

tions. The AAT3681A/-1/-2/-4/-5 is rated for operation

from -40°C to +85°C. In the event of operating ambient

temperatures exceeding the power dissipation abilities of

the device package for a given constant current charge

level, the charge control will enter into thermal limit.

The AAT3681A has four basic modes for the battery

chargeꢀ cycle:ꢀ pre-conditioning/trickleꢀ charge;ꢀ constantꢀ

current/fastꢀcharge;ꢀconstantꢀvoltage;ꢀandꢀchargeꢀtermi-

nationꢀ(seeꢀFigureꢀ1).ꢀ(AAT3681A-1ꢀandꢀAAT3681A-4ꢀdoꢀ
