Typical Application Circuit
Description
The HX6001 is a complete constant current/constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the HX6001 ideally suited for portable applications. Furthermore, the HX6001 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 HX6001 automatically terminates the charge cycle when the charge current drops to 1/10th?the programmed value after the final float voltage is reached.
The HX6001 converters are available in the industry standard SOT-23-5L power packages (or upon request).
Applications
?? Charger for Li-Ion Coin Cell Batteries
?? Portable MP3 Players, Wireless Headsets
?? Bluetooth Applications
?? Multifunction Wristwatches
