一,产品概述(General Description)
        The JTM8010 is a complete constant-current/constant voltage linear charger for
single cell lithium-ion batteries. Its package and low external component count make the
       JTM8010 ideally    suited for portable applications. Furthermore, the JTM8010 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 JTM8010 automatically terminates the charge cycle when the charge current drops to
1/10th the programmed value after the final float voltage is reached.
     The JTM8010 converters are available in the industry standard DFN3*3-10L power packages industry standard DFN3*3-10L power packages
