Abstract
An accumulated current counter () includes a sense resistor () configured for being coupled in series between an electronic circuit () and a power source (). The sense resistor is further for use in sensing a voltage (V) across the sense resistor as a function of a current (Ibatt) provided via the power source. An incremental counter () is coupled to the sense resistor for incrementally counting an amount of current, corresponding to an average value of charge Q, going (i) into or (ii) out of the power source. A register () accumulates a representation of the incrementally counted current. In one embodiment, the representation of incrementally counted current corresponds to a remaining power source life in hours and minutes.
