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.
