Measuring power consumption of ciruit component operating in run mode

A method of detecting and handling power consumption events associated with a circuit component included in an integrated circuit (IC) chip, the method comprising:

• measuring a voltage drop across a resistor coupled to a power terminal of the IC chip;
• amplifying the voltage drop using an on-chip amplifier;
• comparing the amplified voltage drop to one or more voltage references defining limits for over current or under current conditions;
• and
• determining a power event based on results of the comparing.

A circuit for obtaining measurement data from a circuit component included in an integrated circuit (IC) chip, the circuit comprising:

• an amplifier, included in the IC chip, and configured for amplifying voltage drop across a sense resistor coupled to the IC chip;
• an analog-to-digital converter (ADC), in the IC chip, and configured for converting the amplified voltage drop to digital data;
• a clock configured for determining a time of measurement;
• and
• memory configured for storing the time and digital data.
