The resistors R1 and R2 are applied to terminals 1 and 8, respectively, of the switched-mode power supply 26. These resistors R1 and R2 are current-limiting resistors and function to control the output power and current. A standard buck regulator may be coupled to terminal 5 of the switched-mode power supply 26. The buck regulator includes a diode D7 and an inductor L1. The diode D7 and inductor L1 provide DC rectification and filtering of the high-frequency switch voltage from the switched-mode power supply 26.
What is claimed and desired to be secured by a Letters Patent of the United States is: 1. A battery charge indicator for sensing and indicating various states of charge of a lithium ion battery, the battery charge indicator comprising:a current sensing circuit for sensing charging current to said lithium ion battery during a constant current mode of operation and a constant voltage mode of operation and providing a first charge indication signal based upon comparing the magnitude of said charging current with a first predetermined value and generating a ...
