Abstract: A method of detecting a leakage path in an electronic device includes iteratively performing operations until an iteration condition is satisfied. The operations include causing a capacitor to be set to a known state, measuring a voltage level of the capacitor, and storing data indicating the measured voltage level. The operations also include causing the capacitor to be connected to a potential leakage path, remeasuring the voltage level of the capacitor, and storing data indicating the remeasured voltage level. The operations further include comparing the measured voltage level and the remeasured voltage level to detect leakage in the potential leakage path. The iteration condition is satisfied when a difference between the measured voltage level and the remeasured voltage level satisfies a voltage threshold or when a count of iterations performed satisfies an iteration threshold.
