Voltage Glitch Detector

​The Voltage Glitch Detector is a fully integrated analog IP intended to monitor the voltage supply so as to protect the system against fault injection attacks.

Key Features

​Dual-slope detection
Extended slope range
Configurable thresholds
Core and HV versions
Silicon proven​


  • detection of the positive and negative supply voltage glitches
  • two versions available:
