Abstract
Improved techniques for sensing and reporting consumed power are disclosed. The disclosed techniques comprise an integrated circuit solution for sensing power. In some embodiments, such an integrated circuit comprises a resistor on which a sense voltage sensed across an external resistor in response to a load current is mirrored and an analog-to-digital converter configured to regulate the voltage across the resistor and output a binary value representing power. The binary value representing power may integrate one or more electrical or environmental parameters such as current, voltage, temperature, battery voltage, etc.
