Part Details:

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 Charges single cell li-ion batteries directly from Description USB port The STBC08 is a constant current/constant Preset 4.2V charge voltage with 1% accuracy voltage charger for single cell Li-Ion batteries. No Charge current monitor for gas gauging external sense resistor or blocking diode is required. Automatic recharge Under-voltage lockout The STBC08 is designed to work within USB power specifications. An internal block regulates C/10 Charge termination the current when the junction temperature 25µA supply current in shutdown mode increases, in order to protect the device when it Low battery voltage detect for precharge operates in high power or high ambient setting temperature conditions. Soft-start feature limits inrush current The charge voltage is fixed at 4.2V, and current limitation can be programmed using a single DFN6 (3x3mm) package (for better power resistor connected between PROG pin and GND. dissipation) The charge cycle is automatically terminated when the current flowing to the battery is 1/10 of Applications the programmed value. If the external adaptor is removed, the STBC08 turns off and a 2µA current Cellular telephones can flow from the battery to the device. The PDAs device can be put into Shutdown Mode, reducing Bluetooth applications the supply current to 25µA. The device also has a charge current monitor, under voltage lockout, Battery-powered devices automatic recharge. The charge termination and input voltage presence are indicated by two separate status pins. Order code Part number Package
