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.
