一.产品概述kZW嘉泰姆

    The CXLB7343E CXLB7343S is a complete constant-current / constant voltage linear charger for single cell Lithium-Ion batteries. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET 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. kZW嘉泰姆

    The CXLB7343E CXLB7343S automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached. kZW嘉泰姆

    When the input supply (wall adapter or USB supply) is removed, the CXLB7343E CXLB7343S automatically enters a low current state, dropping the battery drain current to less than 0.5uA. The WS4508S can be put into shutdown mode, reducing supply current to 45uA (Typ.). kZW嘉泰姆

    The CXLB7343E CXLB7343S is available in SOP-8L-EP package. Standard product is Pb-Free.kZW嘉泰姆
