AAT3680

Lithium-Ion/Polymer

Linear Battery Charge Controller

™

BatteryManager

General Description

Features

The AAT3680 BatteryManager is a member of

AnalogicTech's Total Power Management IC™

(TPMIC™) product family. This device is a lithium-

ion/polymer battery charge and management IC,

specifically designed for compact portable applica-

tions. The AAT3680 precisely regulates battery

charge voltage and charge current, and is capable

of two trickle charge current levels controlled by

one external pin. Battery charge temperature and

charge state are carefully monitored for fault con-

ditions. In the event of an over-current, short-cir-

cuit, or over-temperature failure, the device will

automatically shut down, protecting the charging

device and the battery under charge. A battery

charge state monitor output pin is provided to indi-

cate the battery charge status through a display

LED. The battery charge status output is a serial

interface which may also be read by a system

microcontroller.
