Abstract
An electrical current measurement circuit is provided. The electrical current measurement circuit is configured to receive a sense current proportionally related to an electrical current of interest to continuously charge a capacitor to a sense voltage. The electrical current measurement circuit is configured to determine whether the sense voltage reaches a predefined voltage threshold and reduce the sense voltage to below the predefined voltage threshold in response to the sense voltage reaching the predefined voltage threshold. The electrical current measurement circuit counts each occurrence of the sense voltage reaching the predefined voltage threshold and quantifies the electrical current based on a total count of the sense voltage reaching the predefined voltage threshold during the predefined measurement period. By incorporating the electrical current measurement circuit in an electronic device, it may be possible to accurately monitor and thus help to optimize power consumption and battery life of the electronic device.
