NCP1800

NCP1800 Single−Cell Lithium Ion Battery Charge Controller The NCP1800 is a constant current, constant voltage (CCCV) lithium ion battery charge controller. The external sense resistor sets the full charging current, and the termination current is 10% of the full charge current (0.1 C). The voltage is regulated at ±1% during the final charge stage. There is virtually zero drain on the battery when the input power is removed.
