The LTC 1732-8.4 is a complete constant-current/constant-voltage linear charge controller for lithium-ion (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% accuracy using external sense and program resistors. An internal resistor divider and precision reference set the final float voltage with 1% accuracy.
