High Effi Ciency, Multi-Chemistry Battery Charger

The LTC4009 is a constant-current/constant-voltage battery charger controller. It uses a synchronous quasi-constant frequency PWM control architecture that will not gener- ate audible noise with ceramic bulk capacitors. Charge current is set by the combination of external sense, input and programming resistors. Current being delivered by the charger CAN be monitored as a voltage across the programming resistor. The LTC4009 features fully adjustable output voltage. An external resistor divider and precision internal reference set the nal output voltage at which charge current will be reduced to zero.
