Product Overview

The LTC1732EMS-4#PBF is a complete constant-current/constant voltage Linear Charger Controller for Li-ion batteries. Nickel-cadmium (NiCd) and nickel metal hydride (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. The SEL pin allows users to charge either 4.1 or 4.2V cells. When the input supply is removed, the LTC1732 automatically enters a low current sleep mode, dropping the battery drain current to 7µA. An internal comparator detects the end-of-charge (C/10) condition while a programmable timer, using an external capacitor, sets the total charge time. Fully discharged cells are automatically trickle charged at 10% of the programmed current until cell voltage exceeds 2.457V.
