Features

Detection of the positive and negative supply voltage glitches
Two versions available:

  • monitoring of the external voltage (vcc) and ground (gnd)
  • monitoring of the internal voltage (vdd) and ground

Slope detection range: 100 MV/s to 2 GV/s (customized on request)
Adjustable detection threshold through a dedicated bus
Typical operating consumption current smaller than 2 µA
