1. A method of obtaining measurement data from a circuit component operating in an ultra-low power mode, the method comprising:

  • charging a capacitor to a voltage level using a voltage source of the circuit component;

    disconnecting the voltage source from an internal power system of the circuit component, enabling the capacitor to power the circuit component;

    responsive to the enabling,starting a counter;

    determining that a voltage across the capacitor exceeds a trip voltage;

    stopping the counter; and

    obtaining measurement data for the circuit component using output of the counter.
