Abstract
In some aspects, a power supply system includes a plurality of power supply devices configured to be connected to an integrated circuit, where a power supply device of the plurality of power supply devices includes a voltage regulator configured to generate a rail voltage, and an internal diagnostic circuit. The internal diagnostic circuit is configured to detect activation of an enable signal to activate the plurality of power supply devices according to an activation power sequence, detect a rail violation of the activation power sequence in response to a value of the rail voltage at a first time, not satisfying a first condition defined by a voltage threshold, or at a second time, not satisfying a second condition defined by the voltage threshold. In response to the rail violation being detected, the internal diagnostic circuit is configured to activate an interrupt signal.
