     CXCH76017 is a complete Current-Limit & constant voltage charger for single cell Lithium-ion and Lithium-Polymer batteries. Its DIP8/COB packages and low external component count make CXCH76017 ideally suited for portable applications. Furthermore, the CXCH76017is specifically designed to work within Universal Travel Charger. CXCH76017has a built-in detector that will automatically detect the polarity of the inserted battery and charge the battery at the correct polarity. The charge voltage is fixed at 4.25V. The SCXCH76017automatically terminates the charge cycle when the charge current drops to 30mA after the final float voltage is reached. When the input supply is removed, the CXCH76017automatically enters a low current stage, dropping the battery drain current to less than 7mA. The CXCH76017can be put into shutdown mode, reducing the supply current to 30uA.
