Overvoltage Comparators
Various comparators monitor the voltage in order to ensure error free operation. The overvoltages must be active
at least 256 periods of tDIG to set the test comparator bits in the SSC Interface registers. This works as digital spike
suppression.
3.6.1
Internal Supply Voltage Comparators
Every voltage regulator has an overvoltage comparator to detect a malfunction. If the nominal output voltage of
2.5 V is larger than VOVG, VOVA and VOVD, then this overvoltage comparator is activated.

VDD Overvoltage Detection
The Overvoltage Detection Comparator monitors the external supply voltage at the VDD pin. It activates the S_VR
3.6.3
GND - Off Comparator
The GND - Off Comparator is used to detect a voltage difference between the GND pin and SCK. It activates the
S_VR bit of the SSC - Interface. This circuit can detect a disconnection of the Supply GND Pin.
