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 7% accuracy. An internal resistor divider and precision reference set the final float potential with 1% accuracy. The output float voltages are set internally to 8.2V
(LTC1731-8.2) or 8.4V (LTC1731-8.4). Complete Linear Charger Controller for
