AAT3681A

500mA USB Port or AC Adapter Li-Ion/Polymer Battery Charger

General Description

Features

The AAT3681A BatteryManager is an integrated single cell

lithium-ion/polymer battery charger IC, designed to oper-

ate from a DC power source or USB port up to an input

voltage of 7.5V. It requires just one external component.

▪

The AAT3681A precisely regulates battery charge volt-

age and current for 4.2V (4.375V option) lithium-ion/

polymer battery cells. When charged from an AC adapt-

er or USB port, the battery charging current can be set

by an external resistor up to 500mA.

•ꢀ AutomaticꢀCurrentꢀSensing

▪

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 automati-

cally shut down, thus protecting the charging device,

control system, and the battery under charge. A status

monitor output pin is provided to indicate the battery

charge status by directly driving an external LED.
