产品概述 返回TOP
CXLB7331 is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. With a thermally enhanced 8-PIN SOP package on the bottom and low external component count make the CXLB7331 ideally suited for portable applications. Furthermore the CXLB7331is 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 / 4.34V, and the charge current can be programmed externally with a single resistor. The CXLB7331automatically 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 CXLB7331automatically enters a low current state dropping the battery drain current to less than 2μA.The CXLB7331can be put into shutdown mode reducing the supply current to 55μA. Other features include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.
