NCP1800

Single−Cell Lithium Ion

Battery Charge Controller

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.
