一.产品概述nrn嘉泰姆

    CXLB7329A is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. Furthermore the CXLB7329A is specifically designed to work within USB power specifications. No external sense resistor is needed and no blocking diode is required due to the internal PMOSFET architecture .Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature .The charge voltage is fixed at 4.2V,and the charge current can be programmed externally with a single resistor. The CXLB7329A 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 CXLB7329A automatically enters a low current state dropping the battery drain current to less than 2μA.The CXLB7329A can be put into shutdown mode reducing the supply current to 55μA. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status.nrn嘉泰姆
