STBC08

800mA Standalone linear Li-Ion

Battery charger with thermal regulation

Feature summary

■ Programmable charge current up to 800mA

■ No external MOSFET, sense resistors or

blocking diode required

■ Complete linear charger for single cell lithium-

ion batteries

DFN6 (3x3mm)

■ Constant current / constant voltage operation

with thermal regulation to maximize charge

rate without risk of overheating

■ Two charge status output pins

Description

■ Charges single cell li-ion batteries directly from

USB port

The STBC08 is a constant current/constant

voltage charger for single cell Li-Ion batteries. No

external sense resistor or blocking diode is

required.

■ Preset 4.2V charge voltage with 1% accuracy

■ Charge current monitor for gas gauging

■ Automatic recharge

The STBC08 is designed to work within USB

power specifications. An internal block regulates

the current when the junction temperature

increases, in order to protect the device when it

operates in high power or high ambient

temperature conditions.

■ Under-voltage lockout

■ C/10 Charge termination

■ 25µA supply current in shutdown mode

■ Low battery voltage detect for precharge

setting

The charge voltage is fixed at 4.2V, and current

limitation can be programmed using a single

resistor connected between PROG pin and GND.

The charge cycle is automatically terminated

when the current flowing to the battery is 1/10 of

the programmed value. If the external adaptor is

removed, the STBC08 turns off and a 2µA current

can flow from the battery to the device. The

device can be put into Shutdown Mode, reducing

the supply current to 25µA. The device also has a

charge current monitor, under voltage lockout,

automatic recharge. The charge termination and

input voltage presence are indicated by two

separate status pins.

■ Soft-start feature limits inrush current

■ DFN6 (3x3mm) package (for better power

dissipation)

Applications

■ Cellular telephones

■ PDAs

■ Bluetooth applications

■ Battery-powered devices
