SINGLE-CHIP, LI-ION CHARGE MANAGEMENT IC FOR

HANDHELD APPLICATIONS (bqTINY™)

FEATURES

DESCRIPTION

•

Small 3 mm × 3 mm MLP (QFN) Package

The bqTINY™ series are highly integrated Li-Ion and

Li-Pol linear charge management devices targeted at

space limited portable applications. The bqTINY™

series offer integrated powerFET and current sensor,

reverse blocking protection, high accuracy current

and voltage regulation, charge status, and charge

termination, in a small package.

•

Ideal for Low-Dropout Designs for Single-Cell

Li-Ion or Li-Pol Packs in Space Limited

Applications

•

Integrated Power FET and Current Sensor for

Up to 1-A Charge Applications

Reverse Leakage Protection Prevents Battery

Drainage

The bqTINY™ charges the battery in three phases:

conditioning, constant current, and constant voltage.

Charge is terminated based on minimum current. An

internal charge timer provides a backup safety

feature for charge termination. The bqTINY™

automatically re-starts the charge if the battery

voltage falls below an internal threshold. The

bqTINY™ automatically enters sleep mode when

V_CCsupply is removed.

•

Integrated Current and Voltage Regulation

±0.5% Voltage Regulation Accuracy

Charge Termination by Minimum Current and

Time

•

Precharge Conditioning With Safety Timer

Status Outputs for LED or System Interface

Indicates Charge and Fault Conditions

In addition to the standard features, different

versions of the bqTINY™ offer a multitude of

additional features. These include temperature

sensing input for detecting hot or cold battery packs;

power good (PG) output indicating the presence of

valid input power; a TTL-level charge-enable input

(CE) used to disable or enable the charge process;

and a TTL-level timer and termination enable (TTE)

input used to disable or enable the fast-charge timer

and charge termination.

•

Battery Insertion and Removal Detection

Works With Regulated and Unregulated

Supplies

•

Short-Circuit Protection

Charge Voltage Options: 4.2 V and 4.36 V

APPLICATIONS

•

Cellular Phones

PDAs, MP3 Players

Digital Cameras
