一,产品概述(General Description)      

   The JTMH6014 is a complete constant-current/constant voltage linear charger
for  single cell lithium-ion batteries. Its package and low external component count
make the JTMH6014 ideally suited for portable applications.Furthermore, the
JTMH6014 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 JTMH6014 automatically terminates the charge cycle when the charge current
drops to 1/10th the programmed value after the final float voltage is reached.
     The JTMH6014 converters are available in the industry standard DFN3*3-10L
power packages (or upon request).
