Abstract
Fault detection circuits and methods. An example of a fault detection circuit includes a comparator configured to compare a voltage at a voltage terminal with a reference voltage, a digital logic circuit coupled to a test terminal and configured to receive, responsive to the voltage at the voltage terminal being less than the reference voltage as indicated by the comparator, a test signal, the digital logic circuit including at least one digital logic gate, and an edge detection circuit configured to (a) monitor a signal produced at an output of the at least one digital logic gate, and (b) based on the signal failing to transgress a threshold within a time period, providing a fault signal indicating detection of a fault at the test terminal.
