■ The LT®1505 PWM battery charger controller fast charges
multiple battery chemistries including lithium-ion (Li-Ion),
nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd)
using constant-current or constant-voltage control. Maximum current can be easily programmed by resistors or a
DAC. The constant-voltage output can be selected for 3 or 4
series Li-Ion cells with 0.5% accuracy. Simple Charging of Li-Ion, NiMH and NiCd Batteries
Very High Efficiency: Up to 97%
Precision 0.5% Charging Voltage Accuracy
Preset Battery Voltages: 12.3V, 12.6V, …
