可编程充电电流800毫安CXLB7255单电池锂离子电池完整恒流恒压线性充电器自动终止充电循环最终浮充电压后电流降至编程值的1/10

产品简介

The CXLB7255 is a complete constant-current/constant voltage linear charger

for single cell lithium-ion batteries. Its package and low external component

count make the CXLB7255 ideally suited for portable applications.

Furthermore, the CXLB7255 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. The charge voltage is fixed at 4.2V, and

the charge current can be programmed externally with a single resistor.37l嘉泰姆
The CXLB7255 automatically terminates the charge cycle when the charge

current drops to 1/10th the programmed value after the final float voltage is reached.37l嘉泰姆
The CXLB7255 converters are available in the industry standard DFN3*3-10L

power packages industry standard DFN3*3-10L power packages
