The HC8010A is a complete constant current /constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the HC8010A ideally suited for portable applications. Furthermore, the HC8010A is specifically designed to work within USB power specifications.
The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The HC8010A automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
The HC8010A converters are available in the industry standard SOP8-PP power packages (or upon request).
