一.产品概述R01嘉泰姆

   CXLB7326 is a constant-current/constant-voltage linear charger for single cell lithium-ion batteries. Its Thin SOT package and low external component count make the CXLB7326B ideally suited for portable applications. Furthermore, the CXLB7326B 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 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. The CXLB7326B automatically terminates he 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 CXLB7326B automatically enters a low current state, dropping the battery drain current to less than 2μA.The CXLB7326Bcan be put into shutdown mode, reducing the supply current to 25μA. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin  R01嘉泰姆
