一,产品概述(General Description)

The JTMH6001 is a complete constant-current constant-voltage linear charger
for single cell lithium-ion batteries. Its package and low external component count
make the JTMH6001 ideally suitedfor portable applications.Furthermore,the
JTMH6001 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 isfixed at 4.2V, and the
charge current can be programmed externally with a single resistor.
The JTMH6001 automatically terminates the charge cycle when the charge
current drops to 1/10th the programmed value after the final float voltage is reached.
The JTMH6001 converters are available in the industry standard SOT-23-5L power packages (or upon request).
