The MAX745 evaluation kit (EV kit) is an assembled and
tested PC board that implements a step-down, switching
power supply designed for charging lithium-ion (Li-
Ion) batteries. The output voltage can be set for one to
four cells. The cell voltage can be set between 4.0V
and 4.4V, with 0.75% accuracy, using standard 1%
resistors. Two LEDs indicate the charging status.
The MAX745 should be used to charge only Li-Ion battery
packs. To charge other types of batteries, use the
MAX1648 or the MAX712/MAX713. To charge SMBus™
smart-battery packs, use the MAX1645/MAX1647/
MAX1667.
