The HC8012 is a complete constant- current/constant voltage linear charger for
single cell lithium-ion batteries. Its package and low external component count make the HC8012 ideally suited for portable applications. Furthermore, the HC8012 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 HC8012 automatically terminates the charge cycle when the charge current drops to 1/10 th the programmed value after the final float voltage is reached.
