ABSTRACT:
A circuit for determining and reporting the energy consumed by an electronic device having a microprocessor and power supply lines for supplying power to the device is disclosed. The circuit comprises a voltage divider connected for sensing the voltage across the power supply lines and generating a voltage signal indicative of the sensed voltage. A current sense resistor is connected in series with a power supply line for sensing the current passing through the power supply lines and generating a current signal indicative of the sensed current. An analog multiplier is connected for receiving and computing the product of the voltage and current signals, and for generating a power signal indicative of the product of the voltage and current signals, the power signal being indicative of the power consumed by the device. A proportional voltage-to-frequency converter is connected for receiving the power signal and for generating primary signal pulses at a frequency proportional to the voltage level of the power signal, each of which pulses is indicative that a predetermined quantity of energy has been consumed by the device. An opto-coupler, connected to the converter, is responsive to generation of the primary signal pulse for reporting to the microprocessor a secondary signal pulse indicating that a predetermined quantity of energy has been consumed by the device.
