Abstract

An example multiphase power converter circuit includes a first power stage is configured to provide a first phase output signal at a first switching output based on a first control signal. The first power stage includes first open fault detection circuitry configured to disable detecting and/or reporting of an open fault condition responsive to the first control signal. A second power stage is configured to provide a second phase output signal at a second switching output based on a second control signal. The second power stage includes second open fault detection circuitry configured to enable detecting and/or reporting of the open fault condition responsive to the second control signal having a value to turn off the second power stage. The second open fault detection circuitry is further configured to detect the open fault condition based on a voltage at the second switching output.
