Standalone 1A Linear Lithium Battery Charger With Thermal Regulation
CE3211 Series
INTRODUCTION:
The CE3211 is a complete constant-current/ constant-voltage linear charger for single cell lithium rechargeable battery. No external sense resistor is needed, and no blocking diode is required due to the internal P-MOSFET architecture. Furthermore, the CE3211 is specifically designed to work within USB power specifications. Its low external component count makes the CE3211 ideally suited for portable applications. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge current can be programmed externally With a single resistor. The CE3211 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. When the input supply (wall adapter or USB supply) is removed, the CE3211 automatically enters a low power sleep mode, ...
