User’s Guide
Using the High Input Voltage Charger for
Single Cell Li-Ion Batteries
(KIT34671EPEVBE)
1
This User Guide helps the Lithium-Ion (Li-Ion)
battery charger designer understand the MC34671
and its evaluation board. It illustrates the design
procedure when using the MC34671 to design a
Li-Ion battery charger, and the way to get the best
performance from the MC34671.
2
The MC34671 is a low-cost high input voltage linear
charger for single cell Li-Ion batteries in a tiny
2x3mm UDFN package. It features high accuracy
output voltage and charge current. Its high input
voltage of 28V eliminates the over-voltage
protection circuit required in handheld devices. It
uses an external resistor to set the CC-mode
charge current up to 600mA. The end of charge
(EOC) current is preset to 10% of the CC-mode
charge current by the factory. When the battery
voltage is below the trickle charge threshold of 2.7V,
the MC34671 charges the battery with 20% of the
CC-mode charge current. Three indication pins
