Abstract: A system topology may use intentional signal injection to monitor one or more power supply circuits that may supply electrical power to components of the system. The system topology may include voltage monitoring circuitry to monitor the output of the power supply. In some examples, a power supply rail fault may happen either inside or outside of the power supply circuit, but not be detectable by the voltage monitoring circuitry. Injecting a check signal in the presence of an actual fault, may cause oscillations at the output node of the power supply detectable by the voltage monitoring circuitry. Once the check signal, combined with the fault signal, at the output node reaches the monitoring threshold detectable by the voltage monitoring circuitry, the voltage monitoring circuitry may output an indication of the fault to processing circuitry of the system.
