产品概述 返回TOPE5k嘉泰姆
The CXLB7383 is a complete constant‐current/constant‐voltage
linear charger for single cell lithium‐ion batteries. Its SOP
package and low external component count make the CXLB7383
ideally suited for portable applications. Furthermore, the
CXLB7383 can work within USB and wall adapter. No blocking
diode is required due to the internal PMOSFET architecture
and have prevent to negative Charge Current Circuit. 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 CXLB7383automatically terminates the charge
cycle when the charge current drops to 1/10th the
programmed value after the final float voltage is reached.
CXLB7383Other features include current monitor, under voltage
lockout, automatic recharge and two status pin to indicate
charge termination and the presence of an input voltage.
