LT1769 Datasheet | Linear Technology

Features s LT1769 Constant-Current/ Constant-Voltage 2A Battery Charger with Input Current Limiting DESCRIPTIO The LT®1769 current mode PWM battery charger is a simple, efficient solution to fast charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metalhydride (NiMH) and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 2A- - DC current (3A peak current). Charge current can be programmed by resistors or a DAC to within 5%. With 0.5% reference voltage accuracy, the LT1769 meets the critical constant-voltage charging requirement for Li-Ion cells. A third control loop is provided to...
