Abstract
A method and system for monitoring latent faults in power supplies may include a variable voltage source and a logic module that may be coupled to an OR FET circuit. The monitoring system may also include comparators for measuring a voltage drop across a FET and, based upon a value of the voltage drop, may determine a latent fault, such as a short circuit or open circuit across the FET.
