The JTMH6009G is a complete constant current /constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the JTM6009G ideally suited for portable applications. Furthermore, the JTM6009G is specifically designed to work within USB power specifications.YHs嘉泰姆

The charge voltage is fixed at 4.22V, and the charge current can be programmed externally with a single resistor. The JTM6009G automatically terminates the charge cycle when the charge current drops to 1/10^th the programmed value after the final float voltage is reached.YHs嘉泰姆

The JTM6009G converters are available in the industry standard SOP8-PP power packages (or upon request).YHs嘉泰姆
