HX6014 详细介绍

The HX6014 is a complete constant current/constant voltage linear charger for single cell lithium-ion batteries. HX6014's package and low external component count make the HX6014 ideally suited for portable applications. Furthermore, the HX6014 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 HX6014 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
The HX6014 converters are available in the industry standard DFN3*3-10L power packages (or upon request).
