ABSTRACT:
A fault detection and protection circuit can include a comparing circuit (e.g., a comparator or a detector) that can be connected to a power line supplying power to an electronic device being tested. The comparing circuit can be configured to detect a fault in which the power line is shorted to ground. For example, the electronic device being tested may have a fault in which its power terminals are shorted to ground. Upon detection of such a fault, the comparing circuit activates one or more switches that shunt capacitors or other energy storage devices on the power line to ground. The comparing circuit may alternatively or in addition activate one or more switches that disconnect the power supply supplying power to the electronic device under test from probes contacting the electronic device.
