Various comparators monitor the voltage in order to ensure error free operation. The overvoltages must be active
at least 256 periods of t
suppression.

3.6.1
Every voltage regulator has an overvoltage comparator to detect a malfunction. If the nominal output voltage of
2.5 V is larger than V

The Overvoltage Detection Comparator monitors the external supply voltage at the V
bit.(Figure
3.6.3
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.
