HX6009G数据手册HXSEMI中文资料规格书

描述 Description

The HX6009G is a complete constant current /constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the HX6009G ideally suited for portable applications. Furthermore, the HX6009G is specifically designed to work within USB power specifications.\r
\r
The charge voltage is fixed at 4.22V, and the charge current can be programmed externally with a single resistor. The HX6009G automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.\r
\r
The HX6009G converters are available in the industry standard SOP8-PP power packages (or upon request).
