SINGLE-CHIP CHARGE AND SYSTEM POWER-PATH MANAGEMENT IC

Check for Samples: bq24030-Q1 bq24031-Q1

FEATURES

APPLICATIONS

•

Smart Phones and PDAs

MP3 Players

Digital Cameras

Handheld Devices

Internet Appliances

•

Qualified for Automotive Applications

•

Small 3.5-mm × 4.5-mm QFN Package

Designed for Single-Cell Li-Ion or

Li-Polymer-Based Portable Applications

•

Integrated Dynamic Power-Path Management

(DPPM) Feature Allowing AC Adapter or USB

Port to Simultaneously Power the System and

Charge the Battery

DESCRIPTION

The bqTINY™ III series of devices are highly

integrated Li-ion linear chargers and system

power-path management devices targeted at

space-limited portable applications. The bqTINY III

series offer integrated USB-port and dc supply (AC

adapter), power-path management with autonomous

power-source selection, power FETs and current

sensors, high accuracy current and voltage

regulation, charge status, and charge termination in a

single monolithic device.

•

Power Supplement Mode Allows Battery to

Supplement USB or AC Input Current

Autonomous Power Source Selection (AC

Adapter or USB)

Integrated USB Charge Control With

Selectable 100-mA and 500-mA Maximum

Input Current Regulation Limits

•

Dynamic Total Current Management for USB

Supports up to 2-A Total Current

The bqTINY III series powers the system while

independently charging the battery. This feature

reduces the charge and discharge cycles on the

battery, allows for proper charge termination, and

allows the system to run with an absent or defective

battery pack. This feature also allows for the system

to instantaneously turn on from an external power

source in the case of a deeply discharged battery

pack. The IC design is focused on supplying

continuous power to the system when available from

the AC, USB, or battery sources.

3.3-V Integrated LDO Output

Thermal Regulation for Charge Control

Charge Status Outputs for LED or System

Interface Indicates Charge and Fault

Conditions

•

Reverse Current, Short-Circuit, and Thermal

Protection

Power Good (AC Adapter and USB Port

Present) Status Outputs

Charge Voltage: 4.1 V or 4.2 V
