产品概述 返回TOPjvk嘉泰姆
The CXLB7382 is a complete constant‐current/constant‐voltage
linear charger for single cell lithium‐ion batteries. Its SOT23‐5
package and low external component count make the
CXLB7382 ideally suited for portable applications. Furthermore,
the TCXLB7382can 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 CXLB7382automatically terminates
the charge cycle when the charge current drops to 1/10th
the programmed value after the final float voltage is
reached.
CXLB7382Other features include current monitor, under voltage
lockout, automatic recharge and charge status pin to indicate
charge termination.
