Features and Applications

The STC4054GR is a constant current/constant voltage charger for single cell Li-Ion batteries. No external sense resistor or blocking diode is required and its ThinSOT package make it ideally suited for portable applications.

The STC4054 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.

Features:

  • Programmable charge current up to 800 mA
  • No external MOSFET, sense resistors or blocking diode required
  • Constant current / constant voltage operation with thermal regulation to maximize charge
    rate without risk of overheating
  • Charges single cell li-ion batteries directly from USB port
  • Preset 4.2 V charge voltage with 1% accuracy
  • Automatic recharge
  • Single charge status output pin
  • Charge current monitor output for gas gauging
  • C/10 Charge termination
  • 25 μA supply current in shutdown mode
  • Low battery voltage detect for precharge setting
  • Soft-start limits inrush current
  • TSOT23-5L package

Applications:

  • Cellular telephones
  • PDAs
  • Bluetooth applications
  • Battery-powered devices
