LTC4008 - 4A, High Efficiency, Multi-Chemistry Battery Charger

The LTC4008 is a constant-current/constant-voltage charger controller. The PWM Controller uses a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable with a sense resistor and programming resistor to 4% typical accuracy. Charging current CAN be monitored as a voltage across the programming resistor. An external resistor divider and precision internal reference set the final float voltage.
LTC4008 includes a thermistor Sensor input that will suspend charging if an unsafe temperature condition is detected and will automatically resume charging when battery temperature returns to within safe limits; a FAULT pin indicates this condition. A FLAG pin indicates when charging current has decreased below 10% of the programmed current. An external sense resistor programs AC adapter current limiting. The ICL pin indicates when the charging current is being reduced by input current limiting so that the charging algorithm CAN adapt.
