TWO-CELL Li-ION CHARGE MANAGEMENT IC

FOR PDAs AND INTERNET APPLIANCES

Check for Samples: bq24004, bq24005, bq24006

FEATURES

DESCRIPTION

•

Highly Integrated Solution With FET Pass

The bq2400x series ICs are advanced Li-Ion linear

charge management devices for highly integrated and

space-limited applications. They combine high-

accuracy current and voltage regulation; FET pass-

transistor and reverse-blocking Schottky; battery

conditioning, temperature, or input-power monitoring;

charge termination; charge-status indication; and

charge timer in a small package.

Transistor and Reverse-Blocking Schottky and

Thermal Protection

•

Integrated Voltage and Current Regulation

With Programmable Charge Current

•

High-Accuracy Voltage Regulation (±1%)

Ideal for Low-Dropout Linear Charger Designs

for Two-Cell Li-Ion Packs With Coke or

Graphite Anodes

The bq2400x measures battery temperature using an

external thermistor. For safety, the bq2400x inhibits

charge until the battery temperature is within the

user-defined thresholds. Alternatively, the user can

monitor the input voltage to qualify charge. The

bq2400x series then charge the battery in three

phases: preconditioning, constant current, and

constant voltage. If the battery voltage is below the

internal low-voltage threshold, the bq2400x uses low-

•

Up to 1.2-A Continuous Charge Current

Safety-Charge Timer During Preconditioning

and Fast Charge

•

Integrated Cell Conditioning for Reviving

Deeply Discharged Cells and Minimizing Heat

Dissipation During Initial Stage of Charge

•

Optional Temperature or Input-Power

Monitoring Before and During Charge

current precharge to condition the battery.

preconditioning timer provides additional safety.

Following pre- conditioning, the bq2400x applies a

constant-charge current to the battery. An external

sense-resistor sets the magnitude of the current. The

constant-current phase is maintained until the battery

reaches the charge-regulation voltage. The bq2400x

then transitions to the constant voltage phase. The

user can configure the device for cells with either

coke or graphite anodes. The accuracy of the voltage

regulation is better than ±1% over the operating

junction temperature and supply voltage range.

Various Charge-Status Output Options for

Driving Single, Double, or Bicolor LEDs or

Host-Processor Interface

•

Charge Termination by Minimum Current and

Time

•

Low-Power Sleep Mode

Packaging: 20-Lead TSSOP PowerPAD™

APPLICATIONS

Charge is terminated by maximum time or minimum

taper current detection

•

PDAs

Internet Appliances

MP3 Players

Digital Cameras

The bq2400x automatically restarts the charge if the

battery voltage falls below an internal recharge

threshold.
