The EMC5754 is a complete linear charger for single cell
lithium-ion batteries. With small SOT-25 package and
few external components, EMC5754 is well suited for
portable applications. In addition, the EMC5754 is
specifically designed to work within USB power
specifications.
No external sense resistor and blocking diode are
required. Charging current can be programmed
externally with a single resistor. The built-in thermal
regulation facilitates charging with maximum power
without risk of overheating.
The EMC5754 always preconditions the battery with
1/10 of the programmed charge current at the
beginning of a charge cycle, until 40μs after it verifies
that the battery can be fast-charged. The EMC5754
automatically terminates the charge cycle when the
charge current drops to 1/10th the programmed value
after the final float voltage is reached.
