Droop Detector - TSMC CLN4P

Analog Bits’ Droop Detector macro addresses SOC power supply and other voltage droop monitoring needs in
a fully integrated easy-to-use macro. The Droop Detector macro includes an internal bandgap style voltage
reference circuit which is used as a trimmed reference to compare the sampled input voltage against. The
Droop Detector macro is a synchronous with latched output. Only when the monitored voltage input has
exceeded a user-selected voltage level will the Droop Detector output signal indicate that a violation is
detected.
The Droop Detector outputs a core logic level signal, with a high level representing a droop or continuous
voltage above the selected value, and a low level representing a droop or continuous voltage below the
selected value.
