The Glitch Detector macro comprehensively addresses typical SOC power supply and other voltage glitch monitoring needs in a fully integrated easy-to-use macro. The Glitch Detector macro includes an internal bandgap style voltage reference circuit which is used as a reference to compare the voltage supplies against.
The Glitch Detector macro is fully asynchronous with hot outputs, so requires no clock or other synchronizing signal to work correctly. Only when the monitored voltage inputs have exceeded a user-selected voltage level will the respective Glitch Detector output signal indicate that a violation is detected.
The Glitch Detector outputs a core logic level signal, with a high level representing a glitch or continuous voltage above the selected value, and a low level representing a glitch or continuous voltage below the selected value.
