FEATURES

s s s s s s s s s Charges NiCd, NiMH and Lithium-Ion Batteries –– Only One 1/10W Resistor Is Needed to Program Charging Current High Efficiency Current Mode PWM with 1.5A Internal Switch and Sense Resistor 3% Typical Charging Current Accuracy Precision 0.5% Voltage Reference for Voltage Mode Charging or Overvoltage Protection Current Sensing Can Be at Either Terminal of the Battery Low Reverse Battery Drain Current: 3µA Charging Current Soft Start Shutdown Control 500kHz Version Uses Small Inductor plest, most efficient solution to fast-charge modern rechargeable batteries including lithium-ion (Li-Ion), nickelmetal-hydride (NiMH)* and nickel-cadmium (NiCd)* that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 1.5A DC current (2A peak current). The 0.1Ω onboard current sense resistor makes the charging current programming very simple. One resistor (or a programming current from a DAC) is required to set the full charging current (1.5A) to within 5% accuracy.
