Product Summary

The LT1571EGN-2 is a simple, efficient constant-current/ constant-voltage battery charger to fast-charge rechargeable batteries including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd) using constant-current and/or constant-voltage control. The internal switch is capableof delivering 1.5A DC current (2A peak current). The onboard current sense resistor (0.1Ω) allows simple charge current programming to within 5% accuracyusing a low cost external resistor. The constant-voltage output can be selected for 4.1V or 4.2V per cell with 0.6% accuracy. The applications include cellular phones, PDAs, Notebook Computers, Portable Instrumentss and Cradle Chargers for Li-Ion, NiCd, NiMH andLead-Acid Rechargeable Batteries.
