功能特点

产品名称:Standalone Linear Li-Lon Battery Charger with Thermal Regulation热调节线性锂离子电池充电器

产品型号:CYT5055

产品描述:

The CYT5055 is a complete constant-current/constant voltage linear charger

for single cell lithium-ion batteries. Its package and low external component count make the HX6003 ideally suited for portable applications. Furthermore, the HX6003 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. The HX6003 automatically terminates the

charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.

The HX6003 converters are available in the industry standard SOT-23-6L power packages (or upon request).
