batteries. Nickel-cadmium (NiCd) and nickel-metal-hydride (NiMH) batteries can also be charged with constant
current using external termination. The external sense
resistor sets the charge current with 5% accuracy. An
internal resistor divider and precision reference set the
final float potential with В±1% accuracy. The output float
voltage is set internally to 4.1V (LTC1731-4.1) or 4.2V
(LTC1731-4.2). Complete Linear Charger Controller for
1-Cell Lithium-Ion Batteries
