Abstract

See full text

Systems and methods for radiation-tolerant overcurrent detection are disclosed. In some embodiments, an integrated circuit may include a plurality of overcurrent detectors, each of the plurality of overcurrent detectors configured to detect a candidate overcurrent event. The integrated circuit may also include a voting circuit coupled to the overcurrent detectors, the voting circuit configured to indicate an overcurrent in response to receiving a selected number of candidate overcurrent events from the overcurrent detectors. At least one of the overcurrent detectors may be subject to detecting the candidate overcurrent in error, at least in part, due to exposure to ionizing radiation.
