(Li-Ion) batteries. Nickel-cadmium (NiCd) and nickel metalhydride (NiMH) batteries can also be charged with constant current using external termination. Charge current
can be programmed with 7% (max) accuracy using external sense and program resistors. An internal resistor
divider and precision reference set the final float voltage
with 1% accuracy. The SEL pin allows users to charge
either 4.1V or 4.2V cells. Complete Linear Charger Controller for 1-Cell
Lithium-Ion Batteries
