   产品概述 返回TOPwYg嘉泰姆

The CXLB7201F is a complete constant current/constant voltage linear charger for single cell lithium-ion batteries.wYg嘉泰姆

 Its package and low external component count make the CXLB7201F ideally suited for portable applications. wYg嘉泰姆

Furthermore, the CXLB7201F is specifically designed to work within USB power specifications.wYg嘉泰姆

No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. wYg嘉泰姆

The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. wYg嘉泰姆

The CXLB7201F automatically terminates the charge cycle when the charge current drops to 1/10^th the programmedwYg嘉泰姆

 value after the final float voltage is reached.wYg嘉泰姆

The CXLB7201F converters are available in the industry standard SOT-23-5L power packages (or upon request).wYg嘉泰姆
