CXLB7201F Linear Li-Lon Battery Charger， complete constant current/constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the CXLB720

   产品概述 返回TOPNQA嘉泰姆

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

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

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

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

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

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

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

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