<P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for charging a battery. <P>SOLUTION: The apparatus comprises a connector configured to electrically couple to a battery, an adjustable current source capable of supplying current to the connector at a plurality of charge rates, and a network resistor configured to bias the adjustable current source to supply current at one of the plurality of charge rates in response to a digital input signal. The method comprises a step of receiving a digital input signal having a plurality of bits and indicating a desired charge rate for the battery, a step of configuring a resistor network in response to the digital input signal, a step of biasing an adjustable current source using the configured resistor network, and a step of supplying current to the battery at the desired charge rate using the adjustable current source. <P>COPYRIGHT: (C)2012,JPO&INPIT |
