INTRODUCTION: The CE3150 is a complete constant-current constant-voltage linear charger for single cell Li-Ion batteries. It’s SOT package and low external component count make the CE3150 especially well-suit for portable applications. Furthermore, the CE3150 is specifically designed to work within USB Power specifications. No external sense resistor is needed and no blocking diode is required due to internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature. The charge voltage is fixed at 4.2V and the charge current can be programmed externally with a single resistor. The CE3150 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. The CE3150 automatically re-starts the charge if the battery voltage falls below an internal threshold. FEATURES: Programmable Charge Current Up to 800mA No External MOSFET, Sense Resistor or Blocking Diode Required Charges Single Cell Li-Ion Batteries Directly from USB Port Preset 4.2V Charge Voltage with ±1% Accuracy Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating Charge Status Output Pin 30μA Shutdown Current 70μA Standby Current Complete Linear Charger in SOT23-5 Package for Single Cell Lithium-Ion Batteries C/10 Charge Termination Soft-Start Limits Inrush Current Automatic Recharge APPLICATIONS: Cellular Telephones, PDAs Charging Docks and Cradles Portable MP3 Players Bluetooth Applications PIN
